      Set Hint Mode for all classes in `base.v`. · 7d7c9871
      Robbert Krebbers authored
      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`.

      Better Coq 8.6 compatibility · 976c58f3
      Ralf Jung authored
      With Coq 8.6, you can no longer have intro patterns that give more names than
      the constructor has.  Also, patterns with too few names are now interpreted as
      filling up with "?", rather than putting the unnamed parts into the goal again.
      
      Furthermore, it seems the behavior of "simplify_eq/=" changed, I guess
      hypotheses are considered in different order now.  I managed to work around
      this, but it all seem kind of fragile.
      
      The next compilation failure is an "Anyomaly: ... Please report", so that's what I will do.

      Remove CollectionOps class. · 8a431343
      Robbert Krebbers authored
      This class whose name is horrible and purpose is arbitrary seems to be a
      leftover of some experiment with ch2o, a long time a ago.
