While yes, parameter names are usually longer than 1 character, I'm super disappointed that Ruby has introduced this. I hate hate HATE this in JS. Sure, it's easier to write, but my brain always has to do a small double-take as to what I'm looking at while reading as it looks almost identical to destructuring. Also, how is this going to work in function heads? `def foo(bar:)` means that `bar` is a required keyword. Is it going to have to be `def foo({bar:})`? In that case, it's going to come off as a potential style error to many people.
