The problem is the vague term "non-traditional." What I meant by this is
that C++ is not context-free. The expression/declaration conflict can
only be resolved by backtracking. This to me represents a quantum leap
in difficulty that was previously reserved for natural language parsing.
Other programming languages can be expressed as an LR(k) grammar, along
with simple static disambiguating rules.
