New submission from Aaron:
I think I may have found a problem with the code that constructs Infinity from
tuples in the C _decimal module.
# pure python (3.x or 2.x)
>>> decimal.Decimal( (0, (0, ), 'F'))
Decimal('Infinity')
# _decimal
>>> decimal.Decimal( (0, (0, ), 'F'))
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
decimal.InvalidOperation: [<class 'decimal.ConversionSyntax'>]
Also, there is no unit test coverage for constructing these special values from
tuples either. I have provided some that pass with the existing pure python
code and with the modifications to the _decimal C code.
The unit tests can be applied to Python 2.7.x as well, if desired. They would
go in the ExplicitConstructionTest.test_explicit_from_tuples() method.
