Hm, my Java complains that that method (lc.getNextSibling()) can't be  
found in class antlr.Token.

But simply factoring the statements out into another production helps  
on first glance.

Too bad Antlr didn't complain about my wrong syntax.  I kept thinking  
it was legal code (maybe because the statements even was wrapped in  
() which makes it look like a single element)...


Thanks!
