T.120: Use template metaprogramming only when you really need to

Choosing takes the form of voting: in the usual case there are about a dozen members on the committee. One topic that is guaranteed to get a high score is template metaprogramming, which I shall henceforward refer to as TMP. This is an exciting field of development in C++ because it promises so much, and yet it often does more harm than good: this is yet another manifestation of the shiny hammer syndrome.
