Maybe the Python parser can be made to add an implied multiplication

could write:
(2.5HOUR - 14MINUTE + 9300MILLISECOND).total_seconds()
This strikes me as quite a nifty idea, if the implied multiplication
calls (by default) __rmul__ on the second operand. A ridiculously
simple example:
>>> import datetime
>>> class D(object):
def __rmul__(self, LHS):
return datetime.timedelta(days=LHS)
>>> # Possibly some magic to make D a singleton class
>>> d=D()
>>> 2*d # Works now
datetime.timedelta(2)
>>> 2d # Does not work now
datetime.timedelta(2)
There would, sadly, be a conflict with
floating literals such as "2e3"
hex literals such as 0XB
complex literals such as 4j
numeric literals such as 1_234
any others I haven't thought of
So the parser would have to give priority to such existing, valid forms.
