On the other hand, having round with a second parameter to return a Decimal
would be quite usefull. I can't see a way of changing the type returned
by the built-in round without crashing half the World --- but maybe it would
be possible to deprecate only the two-parameter form of the built-in round,
and add a decimal.round Decimal factory?
