[sigc] TypeLists!!!

["Lemings, Eric B." <Eric Lemings ngc com>]

The current Libsigc++ API (2.0.3) is in desperate need of
typelists.  Typelists would make the API much simpler and
easier to use.  Has this been proposed/discussed before?

See Modern C++ Design by Alexandrescu
(http://www.moderncppdesign.com/book/main.html) for more
info on typelists.
