I've thought Python should have this for a long time. But Marc-Andre's
point pretty much shoots it down, unless you make isstring(x) sugar for
isinstance(x, (str, unicode))
Hmmm. It's a very small dose of sugar, but I like it all the same.

Note that a certain infamous April Fool's post from a few years back
said that that was what Python 1.6 would do. I wasn't serious,
either. ;-)
