Should one prefer STL algorithms over hand-rolled loops?

Question

I seem to be seeing more \'for\' loops over iterators in questions & answers here than I do for_each(), transform(), and the like. Scott Meyers suggests that stl algori

It depends, if the algorithm doesn't take a functor, then always use the std algorithm version. It's both simpler for you to write and clearer.

For algorithms that take functors, generally no, until C++0x lambdas can be used. If the functor is small and the algorithm is complex (most aren't) then it may be better to still use the std algorithm.
