That doesn't fit the pattern. why do you have extra parens?
from antlr4.
oh, the parens are the problem? They are superfluous, agree. A relic of the non-left recursive (name .)* name form. However, should the parser rely on simple pattern matching for detecting mutual left recursion? I dont think that extra parens should ever change the semantics of a grammar file.

Hi. No doubt the computation is undecidable or close for arbitrary grammars. I am doing a pattern match for only those grammars that will work with the generated code pattern. It is a fairly complicated precedence parsing mechanism. I must be able to determine the operators, which would be quite difficult for arbitrary grammars.
