The examples of pass-as-a-function shown by the Original Poster don't
give any clue of what advantage there is to make pass a function.
Just read the text, it just struck me how similar pass and print are,
i.e. that neither actually needs to be a keyword. In some cases, I would
rather use "return" to replace "pass" though.
It appears that the only reason for this suggested change is that he
would rather write "pass()" instead of "pass", possibly because he
thinks it looks cool.
I have no idea where you got the "cool" from, it is not in my posting. I
stated clearly that "I just had an idea", which should signal that I
haven't thought about this for any extended period of time. Then I asked
"What do you think?" exactly because I wanted to discuss this. No need
to get defensive. ;)
(Actually, I reckon that what is driving this idea is that the OP is a
beginner, and he's got a syntax error a few times from writing "pass()",
and so he thought it would be easier to force other people to change tens
or hundreds of thousands of Python programs to use "pass()" instead of
"pass" than to just learn to stop putting parentheses after it.
So, and in order to force people to write parens or break their code I
have considered the possibility of importing that feature from
__future__ for those people that want it? Seriously, Steven, as much as
I like your regular contributions here, this time you had better logged
off and taken a walk, because you come across as _very_ arrogant here.
But of course I could be wrong. Ulrich, if you are still reading this, if
you have good examples for how pass as a function would actually be
better, and how it will let you do things in Python that can't easily be
done now, I'm very interested to hear them. Who knows, if the idea is
good enough, some day it may even happen.
No there is nothing that you strictly need a pass() function for.
In summary, after reading this thread I have a lot of good arguments
against this idea and few arguments supporting the idea. In any case I
have many more arguments than those that I came up with myself, which is
exactly what I asked for.
Thanks to all that took part in this discussion!
