Macros Macros play a special role in TMP. Some programmers consider them a necessary evil and indeed they are necessary, but it’s not obvious they are also evil. Macros must: • Allow the reader to recognize them • Prevent name collisions As discussed in , usually member function names should be actions. Thus empty should be a synonym for make_empty and not for is_empty. However, STL convention is established and universally understood. When in doubt, do as std::vector does. 27 41 Chapter 1 ■ Templates The easiest way to satisfy both requirements is to choose a unique and sufficiently ugly common prefix for all macros and play with lower/uppercase to give extra meaning to the name.
