colors2 = "cyan forest green burnt umber".split() # oops, not what I wanted, quote each separately
It isn't shared by the proposal.
colors2 = %w[cyan forest green burnt\x20umber]
I don't get it. There is weird escaping of spaces that aren't split? That is confusing and a bug magnet. What are the rules for escaping all whitespace, exactly? All the Unicode space-like code points, or just x20?
Plus your example doesn't capture the color "forest green" correctly in any way I can imagine. But I suppose more weird escapes in the middle could do that.
Overall... the proposal becomes incredibly ugly, and probably more characters that are harder to type, than existing syntax.
