This way, type class search will fail immediately on first type class constraint of any of the `fin_map_dom` lemmas if no `Dom` can be found.

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 patch was created using find name *.v  xargs L 1 awk i inplace '{from = 0} /^From/{ from = 1; ever_from = 1} { if (from == 0 && seen == 0 && ever_from == 1) { print "Set Default Proof Using \"Type*\"."; seen = 1 } }1 ' and some minor manual editing

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.

There was not really a need for the lattice type classes, so I removed these.

It is doing much more than just dealing with ∈, it solves all kinds of goals involving set operations (including ≡ and ⊆).

The singleton maps notation is now also more consistent with the insert <[_ := _]> _ notation for maps.

This one (previously solve_elem_of) was hardly used. The tactic that uses naive_solver (previously esolve_elem_of, now solve_elem_of) has been extended with flags to say which hypotheses should be cleared/kept.

The refactoring includes: * Use infix notations for the various list relations * More consistent naming * Put lemmas on one line whenever possible * Change proofs into oneliners when possible * Make better use of the "Implicit Types" command * Improve the order of the list module by placing all definitions at the start, then the proofs, and finally the tactics. Besides, there is some new machinery for proofs by reflection on lists. It is used for a decision procedure for permutations and list containment.

Both the operational and axiomatic semantics are extended with sequence points and a permission system based on fractional permissions. In order to achieve this, the memory model has been completely revised, and is now built on top of an abstract interface for permissions. Apart from these changed, the library on lists and sets has been heavily extended, and minor changed have been made to other parts of the prelude.
