A couple of random comments:
- I feel like it should be possible to get rid of YOMM2_END
  by moving the function body out-of-line or using a lambda
  or something.
- The documentation isn't clear on how the one-definition-rule
  applies (unless I missed it).  My default assumption would
  be that YOMM2_DEFINE for a given overload should appear in
  exactly one translation unit, and that YOMM2_DECLARE and
  YOMM2_CLASS may appear in multiple translation units so
  long as the declarations are identical, but I notice that
  they're /all/ using unnamed namespaces.  All of your examples
  only use a single source file, so I can't really guess your
  intentions from usage either.
- I'm curious why I would ever want to use the "cute" names
  when they're actually longer than the YOMM2 names.
