The relation is this: PyObject_IsTrue() will let you say
ob.selected = True
or
ob.selected = 1
or anything else which Python would evaluate as True using bool(). The
gist of the discussion I referred to (as I interpreted it) was to be as
forgiving of user input as possible (can't remember the expression
Stephen quoted). Since the consensus at that time was to go with
PyObject_IsTrue(), my assumption was we should follow that elsewhere in
the API.

I tried passing strings like '1.2' to PyFloat_AsDouble() and as I
expected, it doesn't return a float value of 1.2. Same type of thing
for PyInt_AsLong().
