20231	django.utils.text.smart_strip does not work with lazy strings (TypeError)	Baptiste Mispelon	nobody	"{{{
#!python

TypeError: Lazy object returned unexpected type.
}}}

This is caused by this line: https://github.com/django/django/blob/master/django/utils/text.py#L359

I don't think the `allow_lazy` decorator can be applied to a generator function so I think the line should be removed altogether.

If we remove the decorator, then lazy strings are evaluated when the generator is called.
This is not exactly backwards-incompatible since this function never actually worked with lazy strings in the first place."	Bug	closed	Utilities	dev	Normal	fixed			Accepted	1	0	0	0	0	0
