Right. I have no problem with declarative programming.

C++ template programming, however, achieves its ends as a "fortunate"
accidental side effect.

If the purpose is to do compile time computation, then the language should be
designed to be clear and understandable for that purpose, whether declarative
or functaional.

Note I am not saying that C++ templates are in themselves confusing for their
original purpose of parametized code generation (although they can be
justifiably criticized), but only that their application to the purpose of
compile time computation is confusing.
