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.	5 years ago
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.	5 years ago
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.	5 years ago
