I don't think the unpredictability that would introduce would be a good idea. I fail to grasp the unpredictability of "the last expression evaluated in the body of a function is its return value".
It couldn't work in Python because statements aren't expressions, therefore I think def foo(): if cond: 3 else: 4 would break (given if:else: doesn't return a value, the function couldn't have a return value), but in languages where everything is an expression (where if:else: does return a value) there's nothing unpredictable about it.
