SE-0257: Eliding commas from multiline expression lists

[jarod (Jarod Long)]

I also find it surprising and deeply concerning that we are considering a wide range of syntactic sugar proposals that are trivial syntax micro optimizations (eliding a single return keyword, eliding syntactically light-weight separators) that do not actual affect the clarity of code, or improve higher level expressivity of the language. There is a recent blossoming of syntactic sugar proposals on the list of similar ilk, and there are far bigger fish to fry. This is a really concerning to me direction to see the community take.

I don't think this is totally fair — I disagree that two syntactic refinement proposals constitutes a wide range. Bigger fish are in fact still being fried, and I see no reason that we shouldn't make a small amount of room for small refinements like this. There will always be bigger problems to address than syntax refinement, but by that logic there will never be a time to address these issues.
