I didn't say "Pass should be a function!" but asked "What do you 
think?". You are assuming lots of things about my goals and jumping to 
conclusions like that I'm complaining about the stupid Python syntax, 
that I'm a frustrated noob, that I want someone to fix that syntax, but 
that is not the case! I'm engaging in a discussion here exactly in order 
to test the idea I had.

...so what do you do when you have an idea? You think about it on your 
own, right? I do so, too, but I also engage in discussions with others. 
See? BTW: I think you missed the implications of this thread's topic and 
the snide remark about forcing people to change their code, i.e. that no 
existing code has to change (apart from the Python implementation, of 
course), even if pass was made a function!
