bool(Lea) doesn't raise an exception

[Paul Moore]

From the code in lea.py it looks like bool(lea_value) is intended to raise an exception, but it doesn't seem to do so:

>>> from lea import Lea
>>> bool(Lea.fromVals(True))
True
>>> bool(Lea.fromVals(False))
True

[Paul Moore]

This is because the __nonzero__ method is named __bool__ in Python 3. Adding __bool__ = __nonzero__ fixes this.

[Pierre Denis]

Well spotted! You're perfectly right. I'll do the fix that you suggest, although in a converse way because I prefer the cleaner Python 3 to be the baseline:

    def __bool__(self):   ## <--- renamed!
        raise ...
    # Python 2 compatibility
    __nonzero__ = __bool__

You can see this pattern for Lea.__div__ and Lea.__rdiv__.
