No, if it were easy to remember, you wouldn't need this mnemonic. I'm not
saying it's impossible to learn. I'm saying that it's sufficient
bizarre-looking that if -- like me -- you use it fairly rarely, you have to
waste time looking it up to be sure.
Consider for example, that the position of the conditional in a standard
Python if-else structure is right after the condition:
Which suggests the reversed order, doesn't it? Again, I'm not looking for
a mnemonic to help me with C (I've pretty much abandoned it for most
purposes, anyway). I'm trying to say why I think newbies will be turned
off by this syntax.
Pointer syntax isn't that hard to remember either -- but it was
sufficiently confusing to avoid doing it in Python.
