Well, yes.  But that brings in all the other cruft in somelib, when we just
wanted somefunc.

We could also use

    from somelib import *

<1.0E-5 wink>

Now we are getting dangerously close to saying something like "don't ever use

    from somelib import somefunc

because we don't know the exceptions or how the exceptions are defined."

The original point of the thread, IIRC.
