Yes.

This is almost the only reason why I would want such (more powerful)
aliases: to have a way to define them built in. If we ever decide to
change widgets to accept arguments and to make some of the builtin
widgets aliases to them at all, we can of course easily hide this
completely from the users. They will still only be able to use `-A'
but internally we use aliases with arguments and document it as `foo
behaves like bar with arguments...' or something like that.
