> The most sensible approach is to break out bigint/bigrat when it is needed. ... Python does it

Really? That's surprising me a bit... can you provide evidence for this?

From my experience is Python "more" typed than Perl, leading to 3/2==1 because it assumes that's an integer operation only.

OK, looks good in Python3, seems they also fixed the division issue from Python2

Seems like 128/2 being a float, breaks the workaround xD
