[antlr-interest] Question

[Bill Andersen]

Folks,

I have a grammar (relevant snippet below) with which I'm having a  
parsing problem.  (I'm using ANTLR 3.1 in a beta release of ANTLRWorks  
FWIW)

term
	: NAME
	| LP term+ RP
	;

atom
	: LP term+ RP
	;

LP
	: '('
	;

RP
	: ')'
	;

NAME
	: ('a'..'z')+
	;

WS
	:  (' '|'\t'|'\n'|'\r') {$channel=HIDDEN;}
   ;

Attempts to parse "( foo )" in ANTLRWorks' interpreter as a 'term'  
fails. while parsing "( ( foo ) )" as an 'atom' succeeds (i.e. I'm  
seeing the correct parse trees).  Note that the former 'term' is  
embedded in the latter 'atom'.  Am I making an obvious mistake?  Any  
help appreciated.
