I don't really disagree with most of what you wrote! And agree that decorators,
specifically, are a pretty good solution within the scope of an individual
package.
But I would quibble with this:

The delayed execution of a generator function is, IMO very, very different than
a regular function!
```
def f():
result = side_effect1()
yield 0
yield 1
return result
```
vs.
```
def f():
side_effect()
return range(2)
```
These are contrived examples, obviously, but I've specifically encountered
issues like this when working with code that handles streaming data - from a db
or REST API, for instance. My experience of this type of code is often along
the following lines:
```
def stream_rows(self):
[mutex handling ...]
[retry logic]
[more mutexes?]
[some timeout stuff]
[...]
```
I don't mean to belabor the point - the decision in PEP 255 is pretty
definitive, and this was more or less a "modest proposal" anyway. I do
appreciate the responses and discussion!
Thanks,
Aaron
