This is not fair, you are usingthe preprocessor ;-)

In message 15227, I wrote

-> Interface 2 has the advantage that it is used
-> in the standard C++ algorithms.
-> It has the disadvantage that there is no possibility
-> (or at least that I do not know one)
-> to switch to interface 1 without writing
-> a second wrapper algorithm for every existing standard algorithm.

Your macro is exactly this possibility.
I do not like it, because it uses the preprocessor,
and Bjarne Stroustrup likes to se the preprocessor abolished.
Now it comes again through the backdoor...

This is again an example where the simplicity
of the preprocessor helps to work around language restrictions.
