Yes :). Citing the "Description" section:

"copy is, in fact, just another name for fold. It was introduced for
symmetry with copy_if [1], and because it's a nice name for one of the
typical fold applications, that is, copying the content of one sequence into
another - see the example below."

It was. At some point these templates were near extinction, but somehow they
survived ;). I'll revise the issue for the next revision of the library -
thanks for reminding.

I am not sure how useful it is outside the library - it's pretty simplistic.
If anybody wants it, they are welcome to do the refactoring.

Fair enough. Consider it fixed.

It's a long story. If you are working with a conforming compiler, you can
ignore it. If not, I will explain :).

Thanks for you comments!
