What you call clean up I would call making needlessly verbose. By the same argument, why not “plus” and “minus”?

Symbols are great because they stand out from text, and your variables and class members will be text. There is a reason mathematics uses a lot of symbols as well: It makes it easier to read. There is a learning curve, sure, but the same is the case with text: “and” is that logical or binary and? With symbols, one is && and the other is &.

No, instead it looks like AppleScript :( Catering to beginners is all good, but catering to experienced developers is ultimately more important, I think.
