Proposal: Static sort method on Array

[C. Scott Ananian]

To be super explicit: given an array 'a', then: `Array.from(a).sort()` will
return you a sorted clone.  That works even if `a` has an iterator or is an
array-like object.  That's just seven characters longer than
`Array.sort(a)`, which is what you seem to be proposing.

To be sure, I don't think the wider world (ie, a naive Google search) knows
the full wonders of `Array.from` yet.  I particularly like using it on
strings...
