There's no need to implement everything at once...
In this case, I'm saying that rather than accept the *wrong* argument
(inexact integers), we have a need for larger exact integers than we can
support at present, and the right thing to do is add larger exact
integers, not allow a function which should accept only exact integers
to start taking inexact ones.
