[cfe-dev] Proposal: parsing Qt signals/slots with attributes

The grammar is fairly simple, and one need only look ahead a single token (to the ':') to determine whether we have the signals or slots keyword (vs. using it as an identifier). It shouldn't be much more work than threading attributes through the access specifiers like you've already done.

It seems to me as there is a danger of keyword misinterpretation in non-QObject contexts.
