Macros

Being a template metaprogramming framework, the MPL concentrates on getting one thing done well and leaves most of the clearly preprocessor-related tasks to the corresponding specialized libraries [PRE], [Ve03]. But whether we like it or not, macros play an important role on today's C++ metaprogramming, and some of the useful MPL-level functionality cannot be implemented without leaking its preprocessor-dependent implementation nature into the library's public interface.
