Please allow multiplying timedelta by a Decimal:

Do you have a particular use-case in mind? Is there a reason that td * 0.1 or td / 10.0 aren't good enough?

This is for cases where I already have the number as a Decimal. Asking me to convert it to `float` myself is annoying.

This is similar to issue 14262. If we decide that timedelta should play nice with Decimal, I would like to consider all related features.

Well, it's just a call to 'float', right? On the other side, we're looking at significant extra code to implement Decimal * timedelta, so there needs to be a good reason to add it. (And there's feature-creep involved, too; once we've got Decimal * timedelta, there will probably also be requests for timedelta / Decimal, and possibly timedelta / timedelta -> Decimal too).

In fact, this is a near-duplicate of #14262 becaus instead of
>>> decimal.Decimal('0.1')*datetime.timedelta(seconds=3)
one can always write
>>> datetime.timedelta(seconds=decimal.Decimal('0.1')*3)

Agreed; +1 on folding this into issue 14262.
