 The class `Infinite A` is now defined as having a function `fresh : list A → A`, that given a list `xs`, gives an element `x ∉ xs`.  For most types this `fresh` function has a sensible computable behavior, for example: + For numbers, it yields one added to the maximal element in `xs`. + For strings, it yields the first string representation of a number that is not in `xs`.  For any type `C` of finite sets with elements of infinite type `A`, we lift the fresh function to `C → A`. As a consequence:  It is now possible to pick fresh elements from _any_ finite set and from _any_ list with elements of an infinite type. Before it was only possible for specific finite sets, e.g. `gset`, `pset`, ...  It makes the code more uniform. There was a lot of overlap between having a `Fresh` and an `Infinite` instance. This got unified.

 Rename `gmap.to_gmap` into `gset_to_gmap`.  Rename `gmap.of_gset` into `gset_to_propset`.  Rename `coPset.to_Pset` into `coPset_to_Pset`.  Rename `coPset.of_Pset` into `coPset_to_gset`.  Rename `coPset.to_gset` into `coPset_to_gset`.  Rename `coPset.of_gset` into `gset_to_coPset`. The following `sed` script can be used for the first rename: ``` sed i 's/to\_gmap/gset\_to\_gmap/g' $(find ./theories name \*.v) ``` The latter is context sensitive, so was done manually.

Get rid of using `Collection` and favor `set` everywhere. Also, prefer conversion functions that are called `X_to_Y`. The following sed script performs most of the renaming, with the exception of:  `set`, which has been renamed into `propset`. I couldn't do this rename using `sed` since it's too context sensitive.  There was a spurious rename of `Vec.of_list`, which I correctly manually.  Updating some section names and comments. ``` sed ' s/SimpleCollection/SemiSet/g; s/FinCollection/FinSet/g; s/CollectionMonad/MonadSet/g; s/Collection/Set\_/g; s/collection\_simple/set\_semi\_set/g; s/fin\_collection/fin\_set/g; s/collection\_monad\_simple/monad\_set\_semi\_set/g; s/collection\_equiv/set\_equiv/g; s/\bbset/boolset/g; s/mkBSet/BoolSet/g; s/mkSet/PropSet/g; s/set\_equivalence/set\_equiv\_equivalence/g; s/collection\_subseteq/set\_subseteq/g; s/collection\_disjoint/set\_disjoint/g; s/collection\_fold/set\_fold/g; s/collection\_map/set\_map/g; s/collection\_size/set\_size/g; s/collection\_filter/set\_filter/g; s/collection\_guard/set\_guard/g; s/collection\_choose/set\_choose/g; s/collection\_ind/set\_ind/g; s/collection\_wf/set\_wf/g; s/map\_to\_collection/map\_to\_set/g; s/map\_of\_collection/set\_to\_map/g; s/map\_of\_list/list\_to\_map/g; s/map\_of\_to_list/list\_to\_map\_to\_list/g; s/map\_to\_of\_list/map\_to\_list\_to\_map/g; s/\bof\_list/list\_to\_set/g; s/\bof\_option/option\_to\_set/g; s/elem\_of\_of\_list/elem\_of\_list\_to\_set/g; s/elem\_of\_of\_option/elem\_of\_option\_to\_set/g; s/collection\_not\_subset\_inv/set\_not\_subset\_inv/g; s/seq\_set/set\_seq/g; s/collections/sets/g; s/collection/set/g; ' i $(find name "*.v") ```

This provides significant robustness against looping type class search. As a consequence, at many places throughout the library we had to add additional typing information to lemmas. This was to be expected, since most of the old lemmas were ambiguous. For example: Section fin_collection. Context `{FinCollection A C}. size_singleton (x : A) : size {[ x ]} = 1. In this case, the lemma does not tell us which `FinCollection` with elements `A` we are talking about. So, `{[ x ]}` could not only refer to the singleton operation of the `FinCollection A C` in the section, but also to any other `FinCollection` in the development. To make this lemma unambigious, it should be written as: Lemma size_singleton (x : A) : size ({[ x ]} : C) = 1. In similar spirit, lemmas like the one below were also ambiguous: Lemma lookup_alter_None {A} (f : A → A) m i j : alter f i m !! j = None
↔ m !! j = None. It is not clear which finite map implementation we are talking about. To make this lemma unambigious, it should be written as: Lemma lookup_alter_None {A} (f : A → A) (m : M A) i j : alter f i m !! j = None↔ m !! j = None. That is, we have to specify the type of `m`.

(These instances are not defined for any FinMap to avoid overlapping instances for EqDecision, which may have awkward consequences for type class search).

This happened for example in <[i:=x]>∅, where simpl unfold insert (despite it being declared simpl never) because ∅ reduces to a constructor.

This reverts commit 20b4ae55bdf00edb751ccdab3eb876cb9b13c99f, which does not seem to work with Coq 8.5pl2 (I accidentally tested with 8.5pl1).

This makes type checking more directed, and somewhat more predictable. On the downside, it makes it impossible to declare the singleton on lists as an instance of SingletonM and the insert and alter operations on functions as instances of Alter and Insert. However, these were not used often anyway.

Similar files (gmap, listset, ...) were already in singular form and matched the name of the set/map data type.
