if uavector use ghc's built-in unboxed array operations (as
Data.Array.Unboxed does) then it's necessarily bounded to types
supported by those operations

btw, i have extended this set in my own library by making a class
which has implementation using those operations but may be extended
further. OTOH, nowadays when ForeignArrays becomes as fast as
built-in ones, i don't see any reasons for these built-in operations at
all
