patch:
Apply the patch and run rake install. Now you can increment variables!
I met some pitfalls in working on this small Rubinius hack.
- The parser is
lib/ext/melbourne/grammar.y. The Racc filelib/ruby_parser.yis just a dummy. - To refer a Symbol, MRI uses
rb_internalwhile Rubinius usesrb_parser_symin the parser. rake builddoesn't build the parser again. You have to runrake install.
