Yeah we kinda miscommunicated on this topic. I'll gather what I have and 
see what is worth sharing.
basically, what I tried to do was a generic

BOOST_HAS_METHOD_NAMED(foo, (int,int))

that check for presence of a given method with a given prototypes in 
types with variations to catch or not to catch
const version of a named methods etc. The code is rather simple IIRC as 
it's roaming the internet since ages but
never put into a proper usable macro I think.

I also think we can check what's needed for this and how to put it 
properly. If you think it's worth, maybe we should start
a new topic and work over this.
