[antlr-interest] Re: Lookahead set merging

[Brad Schick]

I just wanted to note that this is really a "why does antlr work 
this way" question rather than a "please fix my grammar" question :)

Pasted the warnings below. Lines 30 and 33 correspond to the two 
lines containing "(variable_qual)?" in the example.

tester.g:30:13: warning:nondeterminism between alts 1 and 2 of block 
upon
tester.g:30:13:     k==1:"["
tester.g:30:13:     k==2:IDENT
tester.g:33:26: warning:nondeterminism between alts 1 and 2 of block 
upon
tester.g:33:26:     k==1:"["
tester.g:33:26:     k==2:IDENT
