Three variables that will be assigned in parallel three values resulting from
the evaluation of the right-hand side of the assignment.

For example, if I write:
[a,b,c] = 2,4,6

a=2, b=4 and c=6 after the assignment.

Since the assignments occur in parallel, you can swap the values of two
variables without having to use a temporary variable:

[a,b] = b,a
works.
