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?
