C++, libstdc++-v3 and, well, error messages

[Robert Dewar]

<<For languages that are LALR(1), I fully agree.  C++ is not such a
language.  Parsing C++ with a bison parser requires all kinds of
ugly hacks (g++ currently does it by an extra pass that sits between
the lexer and the parser, the purpose of which is to do the needed
extra lookahead).

First of all LALR is too strict a requirement these days for parser
generators. Second, it is definitely not such a difficult task to
construct an acceptable grammar. Remember that recursive descent
is LL1 which is weaker than LRK!
