Easy in principle, maybe, but something can be "hard" simply because
of the quantity of rules and special cases you need to cope with. You
still have to account for every single rule in your grammar
specification.


>(3) It's hard for *human beings* to parse this language.


I agree, that is a big C++ issue, especially with templates -
essentially a kind of broken Haskell hacked onto C++ so that
metaprogramming is done with a completely different sublanguage than
that used for normal programming.
