Subject: [ruby-core:53955] [ruby-trunk - Feature #8190] Truly parallel assignment


Issue #8190 has been updated by boris_stitnicky (Boris Stitnicky).


Interesting. @Hanmac, I don't see how it would break "a, b = b, a".
On the contrary, "a, b = b, a" would only break if the assignment
indeed worked sequentially. I share MA's feeling and subscribe under
nobu's opinion. I do not regard design by jury the best approach in
this case.

=begin 
    i = 0
    s = [1,2,3]
    i, s[i] =s[i], 7
    p s
    #=> [1, 7, 3]

s is expected to be [7, 2, 3].
