Defer, ensure library is loaded

[Jason]

I have a variety of scripts that import some large libraries, and rather than create a million little scripts with specific imports, I'd like to so something like

psycopg2 = ensure_imported (psycopg2)

This way, regardless of invocation I can know psycopg2 is loaded, if it hasn't already been loaded. If I just do a normal import 95% of the time I'll be waiting time with a meaningless import.


Can I do that somehow?
