I don't think Seth's facility exists yet, but it has occurred to me
previously that it would be useful when you need to import two different
functions with the same name from two different packages. (Rare but does
happen.) Duncan's solution won't get around that. So it would be nice to
be able to do this

ImportFromAs( 'pack1', 'funca', 'pack1.funca')
ImportFromAs( 'pack2', 'funca', 'different.name.altogether')

in a NAMESPACE file. Useful-- yes. Possible-- I don't know!
