Just to get this right:this proposal is about reversing the order of 
chaining expressions?

Instead of:

b = a + 1
c = b + 2

we could write it in reverse order:

c = b + 2 given/for:
     b = a + 1


If so, I don't know if it just complicates the language with a feature 
which does not save writing nor reading nor cpu cycles nor memory and 
which adds a functionality which is already there (but in reverse order).

Maybe there are more benefits I don't see right now.
