[antlr-interest] Performing an action based on alternative result

[Olivier Dragon]

Hi,

I'd like to be able to define a single label for many alternatives and
then use the result in an action. Something like this:

foobar :
(
	t:"function" |
	t:"subroutine" |
	t:"program"
)
{ doSomethingWith(t) ; }

But ANTLR gives me an error "Label 't' has already been defined". Is
there an easy way to do this so that I don't have to specify different
label for each alternative and the same action for each as well?

Thanks,

-Olivier
