[antlr-interest] Problem #2: template lists expanding to weird stuff?

[Peter Nann]

Now, my grammar has a more serious template using Lists and the '+='
operator.

It is getting rather strange expanded output which looks like:

	<one-of> [@2,2:2='x',<4>,1:2] </one-of>


What the heck is going on there?
It looks like the List object has expanded itself using some strange
toString() method.

Any clues on this one?


Updated grammar:

----------------------
grammar Test;
options {output=template; rewrite=true;}

test
	: '[' ( items+=WORD )* ']'
		-> template(items={$items})
			<< \<one-of\> <items; separator=", ">
\</one-of\> >> ;
	
WORD : ('a'..'z'|'-'|'_'|'\'') ('a'..'z'|'-'|'_'|'\'')* ;
WS : ( ' ' | '\t' | '\r' | '\n' )+ {$channel = HIDDEN;} ;
