 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.

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`.

This is needed to use coqstdpp in developments with typeintype as set_unfold will otherwise unify with any hyp, causing the set_solver tactic to break.
