The example that came in mind to me was datetime, that uses the bits
in the constructor, plus provides conversion function or class methods
to handle the string form:

datetime(year, month, day[, hour[, minute[, second[, microsecond[,tzinfo]]]]])

So like Sridhar, I'd rather have an detailed constructor.

I'm 0- on Tres proposal though, because the string form will be the
most used form.
