Well in my own language commas are entirely optional. They actually only exist for JSON compatibility (ie pasting JSON blobs into the language rather than transcribing the data). But I will concede that having a comma separated list on a single line does at least improve readability for some people. In that particular scenario we are drifting into the laws of diminishing returns and thus things become a lot more subjective. However having a comma terminator when followed by a LF doesn’t. The whitespace is larger and more visible than the comma. In that scenario the comma doesn’t add enough visual distinction to add value to the syntax.
