As I see in usage, this function used as contextmanager, why you remove this (@contextmanager + yield) ?

Oh, it really doesn't work as was expected, nice catch!

After meged comment:

Actually, it was already brokenl. Compare with code:

from contextlib import contextmanager

@contextmanager
def g():
    print("g input")
    yield
    print("g exit")

@contextmanager
def f():
    print("f input")
    yield g()
    print("f exit")


with f():
    print("with block")

This code prints:

f input
with block
f exit

But expected something like:

f input
g input
with block
g exit
f exit

Back to the file_or_filename, methods __enter__ and __exit__ of smart_open(input) or input are not called at all. Oops.

Can you add a test for this?

[horpto]

Hmm, ok. But I don't understand what exactly should I check in it ?

I read full method definition, now it's clear for me, thanks.
