Hi Simon,
I assume you're using the grammar from this project:
http://code.google.com/p/phpparser/
If so, you'll need to modify the grammar to work with any target other than

Here's my analysis of the problem. First and foremost, I'm treating the rule
args as though it were written args : ID+;
Problem 1: The rule args is not always executed behind the same predicate.
This is easily corrected by adding a second rule args2 and modifying the
element rule as follows:
When a semantic predicate is involved with decision making in a grammar, the
following rules should be considered absolute:
1. The predicate cannot access any argument to any rule.
2. The predicate cannot access any variables declared within an @init{}
block of any rule.
3. The predicate cannot
