Templates appeared pretty early in C++, and solved a lot of problems
that used to be solved in C with preprocessor macros.  Template
specialization and template member functions came later.

This is indeed a serious problem, and people are working on it.  I
don't think it's particular to C++ templates.  Any interesting
facility that generates code will have the same issues to some degree.
