Template metaprogramming can be used to easily in the foot with.
The answer is it depends.
Template Metaprogramming (TMP) is 'run' at compile time, so it's not really comparing apples, then there's no runtime cost at all.

I am a fan of static metaprogramming in C++ . I know Java now has generics. Does this mean that static metaprogramming (i.e., compile-time program execution) is possible in Java? If so, can anyone recommend any good resources where one can learn more ...

I discovered template metaprogramming more than 5 years ago and got a huge kick out of reading Modern C++ Design but I never found an opertunity to use it in real life.
