SE-0257: Eliding commas from multiline expression lists

[Douglas_Gregor]

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.

Indeed. Of the recent proposals that we reviewed, two are syntactic tweaks (this and SE-0255), two are providing more-strongly-typed counterparts to existing dynamic features (SE-0252 and SE-0253), two improve numerics support (SE-0251 and SE-0246), and several others make substantive expressibility improvements (SE-0244, SE-0249). Combine that with active movement on property delegates, custom attributes, explicit member wise initializers and variadic generics, I'd say we have a healthy mix of proposals moving through the pipeline.
