  I know that the C++ language syntax is not a context-free grammar. In
other words, the meaning of tokens (eg. the tokens < and >) cannot be
deduced without the context.

  OTOH, it basically only makes the life of compilers and code editing
software harder, not people writing C++. It *is* the duty of programs to
do all the hard work, rather than leaving it to the user. :)

  OTOH, given that it's impossible to know the meaning of the < and >
symbols in C++ without the full context, I assume it will be impossible
to make any matching logic which would work in all cases. I don't really
think it would be a huge loss if those were not included in the
parenthesis matching rules.
