Your looking for partial classes? D doesn't have this as far as I know.
"alias this" should work for more than one value in the future, and then
(I think) you should be able to do something like this:
class XIB : IB {}
class XIA : IA {}
class X : IA, IB {
XIA xia;
XIB xib;
alias xia this;
alias xib this;
}
I was thinking about similar idea. But instead of alias this I intended
to write something like this:
class X : IA, IB {
XIA xia;
void iamethod()
{
xia.iamethod();
}
...
}
You can also use opDispatch and __traits(getMember, ..). Don't know if it
works when implementing interfaces though.
It is not very pretty though...
But you can also solve it with mixin templates:
mixin template XIA {
// all IA methods
}
mixin template XIB {
// all IB methods
}
class X : IA, IB {
mixin XIA!();
mixin XIB!();
}
This would make the code separation easy to manage, but I am concerned
about debugging. How is e.g. gdb able to debug mixins? I think I have
read somewhere in the D or D-learn, that the dmd can produce the file
with mixed-in code for the debugger, but I am not sure how to find it.

It's not string mixins:
mixin template XIA() {
void a() { ... } // regular function
}
class X : IA {
mixin XIA!()
}
XIA is injected into X, so X now looks like
class X : IA {
void a() { ... }
}
