I recently watched Stephen Lavavej's excellent channel9 video 'Core C++, 2
of n' in which he described a nice trick to stop template argument deduction:

template <typename T>
void (T t1, typename std::identity<T>::type t2)
{
}

Browsing the internet for a similar problem, I recently discovered that
Peter Dimov already described this trick in 2002 in 'Template function type
inference with references' comp.lang.c++.moderated.

Boost is more for the libraries, but could it also reserve some space for
documenting these template tricks?
