>> In any event, you shouldn't be worrying about something like overhead until after your base prorgram is written.

Base programs are written. I was just looking into insight about the mechanics behind importing :)
For instance, do these libraries normally lazy load? If you have mod1.mod2 and mod1.mod3 and import mod1 does it usually also internally load mod2/3? import mod1.mod2 (or do from mod1 import mod2) does it avoid any loading of mod3 or does it do that as part of loading mod1?

I suppose this mailing list may not be the correct place to be asking this question since it is geared towards beginner questions.
