This gives an error currently.  Quite properly.  But if *any* use of
`map' type-checks, with those imports, why on earth should this one
fail?  You don't want to remove a wart from the language, you want to
introduce one!
Umm, no, that would still give an error. See definition of "one and  
exactly one".
