It's not the ISO format per se that is special, but parsing of str(x).
For all numeric types, int, float, complex and even
fractions.Fraction, we have a roundtrip invariant T(str(x)) == x.
Datetime types are a special kind of numbers, but they don't follow
this established pattern.  This is annoying when you deal with time
series where it is common to have text files with a mix of dates,
timestamps and numbers.  You can write generic code to deal with ints
and floats, but have to special-case anything time related.
