I don't agree with either of those. Syntax accepted by int() is less
permissive than for int literals (e.g. int('0x1')) which is good
because int is often used to process data form external sources. In
this vain I'm not sure how I feel about int accepting non-ascii
characters - perhaps there should be a separate int.from_ascii
function for this purpose but that's a different subject.

Having float() accept underscored inputs violates IEEE754. That
doesn't mean it's impossible but why bother?
