I certainly cringe at the sight of  its_a.sin().  One of the advantages of
python is that it doesn't impose any one methodology for software development:
while an OO approach may be great for allowing arbitrary function-like objects
to be callable, for example, it doesn't mean that everything under the sun has
to become a method call.  And, though I'm as lazy as Robert (in fact, I've
proven to be lazier than him in the past), my memory also tells me that
Konrad's mathematical sensibilities lean in the direction of sin(x).
