Comment(by draconx):
I agree that the "funny rationals" are a bit too strange a notion,
especially when it comes to defining how arithmetic operations should
behave.
After thinking about it, I'm fond of the toDouble/fromDouble approach as
it seems consistent with the themes elsewhere in the library, except that
it makes it harder to later add floating types that are wider than Double.
I can post this idea to the haskell-prime mailing list for discussion, if
that's the right one.
