P.S: In case you are wondering "why didn't he tried?" is that I had some compiler error (probably SFINAE related) and didn't had the time to dig it more.
That sounds odd to me I used only partial template specialization and just one enable_if in all my code. What compiler are you using ?
This is the compiler (under Windows):
gcc (GCC) 3.4.2 (mingw-special)
And this is the error log:

I didn't succeed in guessing what's wrong, I'll try to get the specific compiler and to perform a pool of tests.
It compiles and works flawlessy with gcc 4.2.2 under Linux.
Interesting enough the obviously "warnable" line in final_overload_base.hpp
static const unsigned int index = -1;
is warned only with gcc 3.4, not with the newer gcc 4.2 also if -pedantic is given.

Truly a strange behaviour. Anyway I changed -1 to UINT_MAX . Marco -- Using Opera's revolutionary e-mail client: http://www.opera.com/mail/
