[plt-scheme] importing a single symbol from a module

Is there a way to import a single symbol `s' from a module `m'?
This seems to work, but feels kludgy:

    (require (rename m s s))

I don't see anything else in the MzScheme manual, but I may be missing
something (again).  I'd suggest:

    (require (from <module-name> <identifier> ...))
