error in return statement

[zorran]

possibly error in return statement:
====
bool fn1(Object o1, Object o2 ) {
	return o1.opEquals(o2); // opEquals return int
}
====

compiler writes:
"Error: cannot implicitly convert expression (o1.opEquals(o2)) of type int to bool"

But:
====
bool fn2() {
	return 1;
}
====
compile ok!
