I find this very useful.

Something similar has been proposed on the MPL to do list:

http://www.crystalclearsoftware.com/cgi-bin/boost_wiki/wiki.pl?MPL_TODO_List

search for "don't work with enumeration types:"

Example code is at:

http://boost-sandbox.sourceforge.net/vault/index.php?&direction=0&order=&directory=cppljevans/mpl

in range_all.zip.  If your enumerators can be used to make tuples or
variants with "named" fields, as done in the:

   cppljevans/tuple_nested_enum_test.cpp

in the vault, I'd be interested.
