5b893c8ec3 Avoid syntax error in yield assignments (fixes #1054) 2016-04-25 19:14:44 -04:00
Richard van Velzen
8571a08a93 Do not attempt evaluating class expressions 
Broadly the same as function expressions - these actually are statements but
we're limited by the inheritance tree.

Fixes #1044

187a0caf9d Add base54.reset() to compress tests 
Without this reset, char counts bleed to next tests. One test had a bad expect clause.

634f231b78 First class block scope 
- Make let, const, and class symbols be declared in a block scope.
- Piggy back on existing catch symbol implementation to get block-aware mangling working
- Make sure unused block-scoped declarations can be dropped
- Don't eliminate a block if it has a block-scoped declaration
- Remove silly empty anonymous blocks left over from drop_unused
- AST_Toplevel now gets to call drop_unused too, since block-scoped variables aren't global!
- Don't consider block declarations global
