There's a problem: x,y,z=5 assumes 5,nil,nil instead of 5,5,5. So the
other assignment operators would be inconsistent in this regard. IMHO, 
"x,y,z += 5,5,5" would be okay, but I will make no effort to push it.

#== and #<< are plain methods. You shouldn't use method names
to discriminate that kind of behaviour.
