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.This grammar is not LL(1) anymore (it's probably LALR now)when seeing "x", it has the choice between testlist_comp and vararglist,and the first one is picked.Python's parser generator only supports LL(1) grammars.
