The following code :
------------------
import std.stdio;
class A {
void foo(A a) {
writefln("A");
}
}
class B : A {
void foo(B b) {
writefln("B");
}
}
void main() {
B b = new B;
A a = b;
assert(a is b);
b.foo(b);
a.foo(b);
}
--------------
outputs:
B
A
This is understandable as B.foo doesn't actually overrides A.foo. But
somehow it's weird to get different outputs while "a" and "b" are
basically the same object. Has anyone else encountered this problem in
real life? Will C+++, java act the same way?
