__autoload is not called at the time of import, only when the alias is
actually used, so there are actually no performance issues here.

Do we really want this? Since there is no performance improvement having
imports be block-scoped, this really is not needed. IMO, it can also create
confusion, as the same alias means different things in different contexts of
the file.
