Answer 1

Objective C uses + for class methods and - for instance methods — very different interpretation, but it’s the only language I know that decorates methods with plus and minus signs like that;-).

The “name: type” notation (often enriched with a leading keyword such as var for variables and function for functions) was quite popular before C took over the world, most notably perhaps in Pascal (a now-somewhat-obscure language that had a credible bid of its own for world domination not all that long ago;-).
