Oh, I like that - and then we'd have "ensure_lazy" and "ensure_eager"
as callback factories that accepted a predefined list of names.

I think this is going to be one of the key changes in going from
"utility a project implements for itself if it needs it" to "general
purpose language level facility" - I could easily see the simple
predefined list approach working for a *particular* project, but I
think once we open this capability up to all Python users (rather than
only those that are comfortable with customising the import system at
runtime) it will prove to be inadequate.

Cheers,
Nick.
