[antlr-interest] Help with mutually left-recursion

[Nicolai Mainiero]

Hello,

I try to write a grammar for Lua and have a problem with mutually  
left-recursion in the grammar definition. Here ist the section from  
the grammar so far.


prefixexp :'('exp')' | var  | functioncall
	;

functioncall : prefixexp args
	     | prefixexp ':' NAME args
	;

var	: NAME | prefixexp '['exp']' | prefixexp '.' NAME
	;

These three rules are my problem. Please has anyone suggestions or  
hints how to rewrite the grammar to remove the mutually left-recursion.

Thanks
	Nicolai
