[Review] SE-0084: Allow trailing commas in parameter lists and tuples

   --- a.swift
   +++ a.swift
    foo(
      x: 0,
   - y: 1
   + y: 1,
   + z: 2
    )

Trailing commas avoid this:

   --- a.swift
   +++ a.swift
    foo(
      x: 0,
      y: 1,
   + z: 2,
    )

You’re arguing that you want to read Swift code written like this?

I wouldn't mind it.

I personally find that style repulsive :-) and I haven’t seen swift code commonly doing it. I’m not sure that we want to encourage it either.

Don't be too harsh :-) This style can be used with much profit when there are several closure arguments:

   foo(
       x: {
           // several lines of code
       },
       y: {
           // several lines of code
       }
   )

Sorry, but this kind of code writing evokes to me the kind of stream-of-consciousness-scripting I was happy to leave behind when I quit perl (or the one *modern* Javascript is ridden with). But I get it, it is an age old psych principle that it is easier for us to ask to be enabled than it is to self-discipline ourselves. I think it is an addiction lambdas have enabled... why would I have to think about the large scale structure of what I do when I can shove a bunch instructions as a parameter. don't get me wrong, i use lambdas a lot in java, but I use method references as soon as it starts to look smell like I am about to stuff all the logic as parameters.
