[antlr-interest] [v3] A Nit-Pick: ! and ? together

Greetings :-

I have a situation where the semicolon at the end of a particular
statement is optional.  I do not need/want that semicolon in the tree
(it is just syntactic sugar).

Given that now in v3 the ()'s are no longer required for the ?, *, and
+ on single items; I tried:

foo1 : bar1 ';'!? ; // error
foo2 : bar2 ';'?! ; // error

foo3 : bar3 (';'!)? ; // works!

foo4 : bar4 (';'?)! ; // did not try this one...


an extremely small issue....
