Huh? In any case, neither gcc 2.8.1 not dec cxx accept your code (they
are both crap, I know...). Could you point me at the section of the
standard were this is discussed?
Concerning your example, I simply do not see how it could be
implemented. Consider the following version:
class Foo {
public:
virtual int bar() { return 10; }
};
class Bar : public Foo {
public:
string bar() { return "ten"; }
};
void baz(int i) {}
void baz(string s) {}
int main() {
Foo *foo = new bar;
baz(foo->bar()); //What code should be generated here???
return 0;
}
I can understand the case where the return type is changed to a
subclass of a class, but not chnaging int to string...

Might be.
