STL friendly operator << doesn't work

[superbonzo]

Compiled fine in C++11 mode

I've just checked the standard and you're right, thanks. As always, vc++ doesn't support it yet ...

Thanks for the support!

(However I have to disagree with monarch_dodra complaints: 1) if I wanted a different seperating sequence, I'd use a "named"' function (or try to write a iomanip-like modifier (don't know if that's possible...)) 2) It is purely debug-mode function/fun/exercise function, I'd never use that in a code of more than 2-3 source files)
