Sorry if I missed the boat, but only just now saw this PEP.

Glancing through the PEP, I don't see mentioned anywhere the SQL
alternative of having a coalesce() function:

In Python, something like this:

def coalesce(*args):
    for arg in args:
        if arg is not None:
             return arg
    return None

Just drop it into builtins, and voila.   No need for lengthy discussions
about which operator to use because IMHO it needs no operator.

Sure, it's not as sexy as a fancy new operator, nor as headline grabbing,
but it is pretty useful.

Just my 2p.
