It already has. Its the desequencing operator idea.

 object a,b,c,d
 sequence z
 z={1,2,3,4}
 |a,b,c,d| ?= z

Also the slice extention that caters for...

   y = z[3,4,1..2]
that would return a sequence {3, 4, {1,2}}

So that together you could do..

 |a,b| ?= z[2,4]

which is equivalent to ...
  a = z[2]
  b = z[4]

The special desequencing operation '?=' is needed 'cos we also want to do 
this...

  |a,b,c,d| = z

which would assign all of z to each of a, b, c, and d.
