Good idea.

I think it's better to have WHEN before DOCSTRING. DOCSTRING is
hardly ever used while WHEN is used frequently.

Seems like a bad idea to me. For one thing, you can use
define-obsolete-{function,variable}-alias before you define ALIASED.
(I think XEmacs requires this.) That won't work in this case.

How can you determine what's the right thing, in that case?
