When designing a library, you've got to admit that some of the functions
will do waste CPU time, or you end up exposing more and more functions
and suffer from combinatorial explosion.  The point, as has been already
raised in this thread, is whether those wastes are worth fixing or not.
And in the case of the transform functions, remember that you can always
implement them yourself.
