Internalization of pattern is done in two phases.
First Notations, syntactic definitions, primitive entries are tackled to build
raw_cases_pattern_expr. Reference are revolved at this time too. Then raw_patterns
are internalized as cases_pattern or applied inductive (dealing with implicit
args, or_pattern refactoring, aliases).
It is more uniform, it allows notations for non fully applied constructors but :
- It does not raise a warning when an identifier is also a global_reference
different than a constructor.
- It looks for implicit arguments twice. (because finding scopes of arguments
asks for implicit arguments).
- It does not deal anymore with constants that evaluates to constructor. (This one
is voluntary, dealing with implicit & notations is already a hell full of bugs
so what will be next step ? Any terms that computes to a pattern ???)
