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?

There is actually a place for things like that, but it hasn't been updated for years, so it's woefully out of date: http://www.boost.org/community/cpp.html I'm really not sure what to do with it. No seems keen to do this kind thing, and http://isocpp.org/ is tracking C++ development articles, so it might be redundant now anyway.
