Okay, I see your point. There arer indeed some strange non-correspondences
between MPL functions and their STL counterparts. For example, copy, which
takes two input sequences and adds the elements of the first to the end of
the second.

In elisp, the docs say:

Concatenate all the arguments and make the result a list.
The result is a list whose elements are the elements of all the arguments.
Each argument may be a list, vector or string.
The last argument is not copied, just used as the tail of the new list.

So I guess that would be a better name for what MPL calls copy.
