As far as i know "int" is not immutable or const by default.
So, why work this code:
[code]
import std.stdio;
class Bar {
}
class Foo {
private:
int _id;
Bar _b;
public:
this(int id, Bar b) {
this._id = id;
this._b = b;
}
// const_behaviour.d(18): Error: cannot implicitly convert
expression (this._b) of type const(Bar) to const_behaviour.Bar
const(Bar) GetB() const pure nothrow { /// <- must be const(Bar)
instead of Bar
return this._b;
}
int GetId() const pure nothrow { /// <- no const(int) is
neccessary. Why?!
return this._id;
}
}
void main() {
Bar b = new Bar();
Foo f = new Foo(42, b);
}
[/code]
