Ditto.

I'm currently reworking one of the Metrowerks containers.  Historically 
I've used a nested class in each container:

        template <bool b> struct chooser {};

to do the compile time testing of iterators (to make sure they really 
are iterators) and dispatching to the correct methods to implement 
23.1.1/9 (the "do the right thing" clause).

But I would just as soon use int2type which is easier to read than 
chooser because of Loki's success (and which works just great with bool 
arguments).  Andrei, with your permission I would like to put 
Metrowerks::int2type in our <msl_utility>.
