Nothing prevents you from writing yield(E) of course -- but you're
arguing that foo(a = yield(b), c) should be enough, no extra parens
required -- no foo(a = (yield(b)), c). Right?
Yes that's correct.
Pros for yield(E):
- backward compatible
But for this to be true, we would need to use the direct-eval
detection hack I mentioned previously.
On the plus side, this would allow for feature detection of generator
support, right? (Is there any other way to detect generator support?)
- easier to read (to my eye)
- it "feels" more correct to me in context of the when-using-send-
value rule
These are subjective enough there's no point in arguing. I hear ya.
Yes, one man's opinion and experience. If others chimed in claiming
the opposite experience, obviously my argument would be moot. But I
hope I'm providing a decent "average hacker" POV for you.
Pros for (yield E):
- consistent with python
- doesn't present any is-it-a-function? ambiguities
These are more objective (no look & feel ;-). There is a borrowing
from Python. There isn't a function call going on.
Agreed. If look-and-feel weren't factors, I wouldn't have brought it
up. ;)
