Right.

Yes. register_autoload doesn't exist yet, I'm still merely
branistroming some ideas.

Why doesn't it make sense to do this when installing pydb? Isn't
installation the exact time when things like this should be done?

These are imported every time ipython starts. register_autoload would
be a persistent operation, i.e. it should only be run only once and
ipython stores the autoload map to somewhere in the ".ipython"
directory which it reads on startup.
