Extension of the recursive notations mechanism
- Added support for recursive notations with binders
- Added support for arbitrary large iterators in recursive notations
- More checks on the use of variables and improved error messages
- Do side-effects in metasyntax only when sure that everything is ok
- Documentation
Note: it seems there were a small bug in match_alist (instances obtained
from matching the first copy of iterator were not propagated).
