1) Why can't you override processToken() in UnaryExpr and set "cond" there?
That's how I thought this could be done, but never tried it.
2) More basic question: Why is this production of the form
("-" | "+")* UnionExpr
instead of
("-" | "+")? UnionExpr
I wonder what the meaning of "+-++-10" would be? :-)
