[antlr-interest] [AntlrWorks] Q: What does AW interpreter do with syntactic predicates?

[Austin Hastings]

I see a dingbox notifying me that AW doesn't evaluate syntactic 
predicates or actions, when I fire up the interpreter.

So what does it do with them? In particular, if I have a rule like:

rule
    : (synpred) => pattern1
    | pattern2
    ;

What will the interpreter do? Will it skip the synpred but check for 
pattern1? Will it skip the whole thing and go straight to pattern2? Or 
something far more sinister?
