There is the https://github.com/mnmelo/lazy_import which has a `lazy_callable` that provides functionality similar to the `lazy_function` in this PR. The package has received no new commits since 2018, so I decided...

For performance I inlined the function lookup in `__call__`. For a very simple function the `lazy_function` overhead goes down from ``` 237 ns ± 5.31 ns per loop (mean ±...
