There is no real technical reason for it not to work. From a grammer point
of view, 

  for left, right:value in dict:

would also work fine. (the grammar would be:

  'for' exprlist [':' exprlist] 'in' testlist:

and since there can't be a colon inside an exprlist, it's not ambiguous.)
The main problem is whether you *want* that to work :)
