-1, it would be better to change one of the other sum functions (either math.fsum should work with non-floats, or builtins.sum should do the right thing with floats).  It's confusing to have multiple functions that do more or less the same thing, and more so when the reason for having multiple versions is due to complexity in the semantics of floating point numbers.
