Thanks for the first review - i'm glad you like it.

yep - that would be cool!
(though still a long way to go)

It's Hebrew and used in PHP - see
A bit hard to work with (I copy&paste the name all the time)

Changed as you suggested.

>>  -> functionCallParameterList ;;

you mean I should remove the "| 0" from the rule, for example:
#parameters=functionCallParameterListElement @ COMMA ->
functionCallParameterList ;;
LPAREN (parameterList=functionCallParameterList | 0) RPAREN -> foo;
instead of:
#parameters=functionCallParameterListElement @ COMMA | 0 ->
functionCallParameterList ;;
LPAREN parameterList=functionCallParameterList RPAREN -> foo;

> Also, "parameter" should be a list here ("#parameter") if I get that right.

(I do now understand how this works :D)

I'm always happy about constructive criticism!
