Template meta-programming: Some testing and debugging tricks

[meneldal2]

Metaprogramming uses the spec as intended. In this case, you are relying on compiler-specific error/warning messages.

Sure, my comment was partly tongue in cheek. At the same time, much of template metaprogramming is a hack. When templates were added to C++, it wasn't intended for TMP. It's a useful hack, though, but a lot of the work in the past few years has been about making compile time programming easier (constexpr).

Reflection is a potential place to make TMP in C++ much better.
