Jesse A. Tov 87cc90839d Updated tests. 5 years ago
Jesse A. Tov 785af47262 Inlines `begin-with-disappeared-uses`, which means the big indentation 
change is in this commit instead of the previous one.

Jesse A. Tov c8851d31c5 Fixes Check Syntax arrows for lexer generator. 
There was a bug in disappeared-use tracking--a missing
syntax-local-introduce. This change uses `with-disappeared-uses` and
`syntax-local-value/record`, instead of the (broken) manual tracking
that was present before.

I believe that non-BR parser-tools also has this bug, but I haven't
ported the fix yet.

Jesse A. Tov f8c3f37646 Fixes bug demonstrated by previous commit. 
Now (repetition 1 1 e) is a charset if e is a charset, but other number
of repetitions are not.

Jesse A. Tov 0eecc81e6c Demonstrates bug in char-complement. 
This commit adds 3 tests. All 3 should pass, but right now 2 of them
fail because char-complement is considering (repetition n n e) to be
a charset for *any* n, so long as e is a charset.
