Returning void instead of int in the example break assignment
chaining a = b = c. Besides, how such implicitly defined
functions may call user defined code (check input validity,
call events, etc.)?
It should not if evaluating the value of (b = c) will call
getter for b.
Why getter and not setter? Expression a = b = c = d should call
getter for d and setter for rest of them. And if c setter
returns void the chain breaks.
"a = b" calls setter
"(a = b)" calls setter first, getter second
"x = b = c" is same as "x = (b = c)" thus calls setter, then
getter and then setter again
I don't know how it is done know, but that is quite logical
C-like approach based on the fact that result of expression (a =
b) is equal to a.
