No bites? I'd have thought there'd be a few crazy ideas thrown out in
answer to this.

What if it's worded as a feature for interactive Python? Save you the
trouble of explicitly importing modules, by auto-importing them in
response to usage. In theory, it's as simple as adding __missing__ to
globals(), but I don't know of a way to do that for the main module.
