Piotr, something similar was proposed here:

http://groups.google.com/group/comp.lang.c++.moderated/browse_thread/thread/364c0dd5ce512497#

however, the response there indicates the code would be faster with a
switch.  I don't really understand why, especially if the array of
pointers was a constexpr, but then I'm not compiler writer.
