Raymond:

I propose to remove them as explicit methods because
the same behaviour can be achieved with the builtin
functions:

>>> Decimal("NaN").max(Decimal(8))
Decimal("8")
>>> max(Decimal("NaN"), Decimal(8))
Decimal("8")

(in the docs you put that .max() should return NaN if
either is a NaN, but it's not showing that behaviour
(and couldn't find any docs where says that it must to)).

I'm assigning this to you to have your opinion, but if
you're ok I can do the cleaning (code and docs).

I'm putting this as priority 6 because it will be more
painless to take them away before 2.4 final.

Regards,
