That should only happen if the C version did not build for some reason:

Python 3.6.0a0 (default:323c10701e5d, Dec 14 2015, 14:28:41) 
[GCC 4.8.4] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from decimal import Decimal
>>> Decimal("100.00")._int
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'decimal.Decimal' object has no attribute '_int'
>>>
