[antlr-interest] Question regarding "Assignment"

[Lucien Antlr]

Hi folks,

Still wrestling with the ins and outs of the tool, I came up with something I expected to work but that didn't.

I expected lab=(EQ expr) to assign the AST to "lab", but rather it always returns a null.

The equivalent  working statement would be either
1)    (labA=EQ labB=expr) -> ^($labA $labB)
or
2)  newRule:   EQ expr;
   (lab=newRule) -> ^($lab) 

Is it a bug that grouping through ( ) doesn't work when assigning to a label?

Cheers,
Luc
