This behavior also exists in Python 2.6. However, in Python 3 an
exception is raised instead, as these kinds of comparisons are
considered incorrect.
Because of that, I'd like Python 3's behavior of raising exceptions on
float-decimal comparisons to be backported to Python 2.6.


As an aside, regardless of Python 3's behavior, there is a big
difference between 2<"1.9" and 1.6 < decimal("2.0"). It seems reasonable
to expect decimal comparisons to be made according to numerical value.
When this doesn't happen, it is better to fail loudly rather than silently.
