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.

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. ;)

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.

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!
