NO

... unless

please don't use this

no seriously. I do not need another joke package of mine to be deemed "critical" to pypi ¹

ok how do I use it

1. pip install future-lazy-imports
2. add # -*- coding: future-lazy-imports -*- to the top of your file (second line if you have a shebang)
3. use lazy import ... and lazy from ... as normal!

# -*- coding: future-lazy-imports -*-
lazy from asyncio import run

async def hello():
    print('hello hello world!')

def main():
    run(hello())  # lazily imported!

if __name__ == '__main__':
    raise SystemExit(main())

$ time python3 t.py
hello hello world!

real    0m0.064s
user    0m0.061s
sys 0m0.007s
$ time python3  -c 'import t'

real    0m0.027s
user    0m0.023s
sys 0m0.005s

wow!

problems

this doesn't actually implement the PEP, notably __lazy_imports__ doesn't work also this adds a little bit of overhead to every function (since we don't have the freedom to add code to LOAD_GLOBAL) and I'm pretty sure lambda doesn't work ¯\_(ツ)_/¯

sometimes stacktraces point to the wrong line number (if your function starts with a block statement)
