These aren't very interesting metafunctions, since they're all equivalent to mpl::always<implementation_defined> ;-)
Oops sorry perhaps read 'undefined',' user defined' not implementation defined :-)
My point was to say that you are proposing we add something to the library, but you haven't shown us anything but a sketch of a few empty metafunctions. How can anyone comment?
Not to stay that way just havent had time to write some simple examples. (pow_<int_,int_> should be easy!) Could use one of my own but doesnt mean much to many -->
The problem is I have specialised plus, minus, multiplies etc. for use in 'expression templates'. (think is right term). However it would be odd to put these in separate namespace.
