Subject: [ruby-core:53848] [ruby-trunk - Feature #8190] Truly parallel assignment


Issue #8190 has been updated by wardrop (Tom Wardrop).


=begin
Hmm, yeah that request seems reasonable. Right now it seems to be assigning left-to-right. So (({i})) is assigned (({s[i]})), making (({i})) equal to (({1})), only then is (({s[i]})) evaluated and assigned (({7})) as if it's a separate expression on a new line.

Could be a difficult change to make at least in terms of backwards compatibility, but the suggest behaviour is less surprising than the current behavior in my opinion.

=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].
