[antlr-interest] common prefix on Parser rules.

Hello, this is more a grammar design question but antlr related ;)

Look:

Supose I have the next grammar description:

MemberExpresion: new  MemberExpression Arguments

NewExpression: new NewExpression | MemberExpression


Obviously the new prefix is causing a non-determinism escenario. Any
suggestion for transforming this description to let antlr generate a
correct parser?

MemberExpression has others rules too, not just "new MemberExpression
Arguments".


Thanks  a lot in advance.
