The default / operator is not going to do integer division. This is not negotiable; normal people expect 1/2 to mean one half, so / is going to coerce to some type that can support fractions. We'll use "div" and "mod" for the polymorphic variants defaulting to floor semantics, and things like ediv and emod can in turn be importable aliases to whichever kind of divmod you like, potentially even overriding the definition of "div" and "mod" in the current lexical scope through the magic of lexically scoped multiple dispatch.
And % should stick to standard floor semantics, I expect. Whether a Num that happens to be an integer prints out with .0 is a separate issue. My bias is that a Num pretend to be an integer when it can. I think most folks (including mathematicians) think that the integer 1 and the distance from 0 to 1 on the real number line happen to be the same number most of the time. And Perl is not about forcing a type-theoretical viewpoint on the user... Larry
