I realise this was opened as a joke, but I actually consider this suggestion to be unridiculous.  I've never felt comfortable with code that does  "if x" rather than "if x != 0.0"  for x a float.

What really makes this a no-go in Python is the equality between floats and ints, and then between ints and bools.  If we want to maintain the invariant that  x == y implies  bool(x) == bool(y)  then we end up making bool(0) and bool(False) true, the latter of which is clearly ridiculous.

So not in Python, but perhaps in some other Python-like language with a notion of 'boolean context'.
