Would that not also make a failure to import an error at the time of
executing the imported piece of code rather than at the place of import?
And how would optional imports work if they are not loaded until use?  Right
now, optional imports are done by wrapping the import statement in a
try/except, would you not need to do that handling everywhere the imported
object is used instead?

(I haven't been following the entire thread, and I don't know if this is a
forest/tress argument)
