What is metaprogramming used for in C++?

Example of use cases for the C++ metaprogramming facilities

Optimization
- Precomputations at compile time
Program configuration at compile time
- Calculating sizes and limits of data structures
  - May lead to the need of functions and abstraction
- Computations on types
- Computations on functions
- Conditional declaration
Assertions at compile time

C++ is not strong in the area of traditional program reflection

Types cannot be accessed at run time - types are not first class objects
