I want use coffeescript function syntax to write python lambda expression so I modified the Grammar file.

atom: ('(' [yield_expr|testlist_comp|vararglist] ')' |
       '[' [testlist_comp] ']' |
       '{' [dictorsetmaker] '}' |
       NAME | NUMBER | STRING+ | '...' | 'None' | 'True' | 'False')
trailer: '(' [arglist] ')' | '[' subscriptlist ']' | '.' NAME | '->' text

but when I write

(x,y=1)->x+y

the parser doesn't go into vararglist.

any help? -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://mail.python.org/pipermail/python-dev/attachments/20130628/60ed2cc9/attachment.html>
