Amy: It's a real word. I use it all the time (of course, I'm a linguist, and I allow the possibility that I picked it up from my linguist chums, though it doesn't seem particularly jargony to me). For me, "disprefer X" means something like "not choose X when other options are available". This is subtly different from "prefer anything over X", quite different from "not prefer X", and totally distinct from "dislike X" or "object to X".

I don't like the first syntax because then you have weird looking code due to all the leading whitespace, and you lose a lot of real estate.

Any fool can write code that a computer can understand. Good programmers write code that humans can understand.

Code explains what and how Documentation explains why.
