The problem is that the vast majority of people who use Decimal want
accuracy.  Decimal(5)+1.1 does not have an accurate answer.  Remind
yourself of this gems from The Python Way:

Explicit is better than implicit.
Errors should never pass silently.
In the face of ambiguity, refuse the temptation to guess.
