Yes, very much!
Mathematica does this and it's very useful.
Trigonometric functions are all nice candidates. exp(), log() also.
All 'mathematical' functions of one argument basicly.
Support for user functions is a good thing also but not as needed as
the basic functions.
The other day I was manipulating some equation and while all the
standard (+ - * ^) operations work, trigonometric functions did not -
it might be useful for equations also, however mapping over lists is
of most use of course.
