Hello all,
as some of you might know, I have started working on a D module for SWIG
quite some time ago. In the meantime, the project is almost ready for
inclusion in SWIG trunk as a full-fledged language module supporting
D1/Tango and D2/Phobos.
However, there is one major blocker left: I need to check if a method
has been overridden for this in a potential subclass (obviously at
runtime), as illustrated below.
---
class A {
void foo( float a ) {}
void foo( int a ) {}
final void bar() {
// Determine whether this.foo( 1 ) and this.foo( 1f ) really refer
// to A.foo( float ) and A.foo( int ) or if they point to a subclass
// implementation – how?
}
}
class B : A {
override void foo( float a ) {}
}
class C : A {
override void foo( int a ) {}
}
class D : B {
override void foo( int a ) {}
}

Until DMD 1.047, I have used a piece of code shown in
http://d.puremagic.com/issues/show_bug.cgi?id=4835, but the casts in
there are no longer enough for DMD to determine which overload is being
referred to.
Now, please tell me that there _is_ a way to do this (D1 and D2, but I
don't mind if have to generate different code for the both)…
