Decimal.__pos__ uses it to return a Decimal instance that has the
default precision of the current Decimal context:
>>> from decimal import Decimal
>>> d = Decimal('0.33333333333333333333333333333333333333')
>>> d
Decimal('0.33333333333333333333333333333333333333')
>>> +d
Decimal('0.3333333333333333333333333333')
