PEP 690: Lazy Imports Again

[brettcannon]

@encukou

With what you’re proposing, how would make the imports within a single module lazy, regardless of -L?

importlib — The implementation of import

@Kronuz

For example, we need the try / except / finally for compatibility with a lot of code which uses the idiom

I totally agree with that and the with block idioms.

@Kronuz

enable_lazy_imports_in_module() is for SciPy use cases, where it’s desirable to have all imports in a module being lazy, without affecting how it currently works anywhere else. We could of course explore other ways of doing it, what would you propose it’d be a cleaner way for this use case?

Not to have that use case . I think per-module flipping like this via a function call is too magical. If you need that level of control then you can manually change things as appropriate as you obviously control the code that will be affected (i.e. the module you are changing import semantics for). What you’re effectively doing is what a __future__ import typically does, so making a module have a side-effect due to importing a module (the exact thing you’re trying to get people not to do ) seems weird.
