Example:

This (0..4) syntax doesn't exist, afaik. Do you mean myRange ==
[0,1,2,3,4]? Given that [1,2] != [1,2], I don't think so. I'm assuming
you meant that as shorthand.
new Array(myRange) #=> [0, 1, 2, 3, 4]
I'm not sure what this gives you over
var Range = function*(start, end) { let i = start; while (i <= end)
yield i++; };
var myRange = Range(0, 4);
new Array(myRange); # [0, 1, 2, 3, 4], but it empties out myRange
[...Range(0, 4)]; # [0, 1, 2, 3, 4]
var charRange = new Range('a', ' d'); #=> ('a'..'d')
Ugh. This is very latin1-centric. What is 'a'..'d', again? a ä á à b ç c
d, perhaps? (Yes, charCodeAt(0) offers a possible interpretation, but
it's somewhat random.) And what is Range('aa', 'bb')? Range('a', 'bb')?
Range('A', 'a')? Keep away from characters; they aren't numbers drawn
from any useful 1-dimensional space.
