I disagree. I _like_ that IPython is only reporting on the current
state of the interpreter and not trying to second guess what I meant.

How would you recommend IPython distinguish between which "xyz" you
meant: the one in site-packages, the one in some package on the python
path, or the one in the folder you're running IPython from?
