I have run into this issue before and it'll simplify some of my rules
now that it's fixed. I believe the other thing that didn't carry into
synpreds was parameterized rules:
a[bool b]
: {b}? c
| d
;
x : (a[true])? => a[true]
| y
;

Subject: [antlr-dev] labels carried into synpreds now
* Labels on tokens, rules carry into synpreds now so semantic
predicates work.
This didn't work since labels were stripped in the synpred and they
weren't
defined in the generated method.
a : x=A z=a {$x.text.equals($z.text)}? A
| y=A a A A
