96a72d67f2 fix: avoid unnecessary dependencies at mkMatcher 
fixes #1237

2a940dd4ae feat: add Expr.collectFVars, LocalDecl.collectFVars, Pattern.collectFVars, and AltLHS.collectFVars 
They are all in `MetaM`.

These are helper functions for issue #1237. We need to "cleanup" the
local context before trying to compile the match-expression.

see issue #1237

09d1530d8e feat: detect unexpected occurrences of match-expression minor premises 
The error message is far from perfect, but it is better than ignoring
the issue and failing later with an even more incomprehensible error
message.

3cf425ba52 fix: pattern hover information 
We annotate patterns with the corresponding `Syntax` during
elaboration, and do not populate the info tree. Reason: the set of
pattern variables is not known during pattern elaboration.

272dd5533f chore: style use · instead of . for lambda dot notation 
We are considering removing `.` as an alternative for `·` in the
lambda dot notation (e.g., `(·+·)`).
Reasons:
- `.` is not a perfect replacement for `·` (e.g., `(·.insert ·)`)
- `.` is too overloaded: `(f.x)` and `(f .x)` and `(f . x)`. We want to keep the first two.
