I don't think you understood my assertion, then. The example that the
original poster gave was using getattr() with a simple string ("foo" +
"bar") for the 'name' argument, and without a default return value (as
opposed to throwing a variable in there, or a string plus a variable
like you did, or a default retval).
I even said you can do some "very powerful things" with getattr, by
which I meant something exactly like you did. What did you think I
meant by that?
