If I understand your use-case, you have a bunch of functions like this:
def spam_subcommand():
import spam
spam.command()
def eggs_subcommand():
import eggs
eggs.command()
With lazy importing, you might have something like this:
spam = lazy_import('spam')
eggs = lazy_import('eggs')
def spam_subcommand():
load(spam)
spam.command()
def eggs_subcommand():
load(eggs)
eggs.command()
I don't see the benefit for your use-case. How would it be better? Have
I missed something?
