Hi, I'm unfortunately in D this construction is not possible to
define:
class A(T){
abstract void method(S)(T arg1,S arg2);
}
As adding S to function declaration makes it not virtual.
But we can add this kind of functionality using mixin templates
mixin template BaseMix(T,S){
abstract
Hi, i want to join two or more tupples in to one, with mixing the

Consider the `coerce` method:

Yeah, it stores the static type. You can use it to get that
then do a normal dynamic cast to test
Hi Variant stores variant.type as not the "highest" in hierarchy.
Like this
A a= new A;
A b = new B; //B:A
Variant bVar=Variant(b);
bVar.type will be typeid(A) not typeid(B). Is this intentional ?
If so is there a way to get "concrete" type of "b" variable like
when passing to template
How to handle this situation:
module typeTest;
class A{
void a(){}
}
class B:A{
int b(){
return 1;
}
}
class C:B,D{
string c(){
return "";
}
override int d() {
return 0;
}
}

You need Tuple, not Algebraic. Algebraic stores only one value
of one type from a set, like Variant.
Thank you for answering. You right if i would want to store all
types of T.. in an Inner
