Many good answers already. I'd like to point out yet another reason why. 
Consider:
for(i=0; i<100; i++) { loop_body }

Here, i is incremented *after* the loop_body. Thus its name, 
post-increment. In ruby there is no way to tell a method to run not 
where it lexically is but after some action. You couldn't even identify 
after what action. After the next yield? After the next statement?
