Andrei Alexandrescu:
I do agree tagged unions should be pushed into the language;
they'd help the GC.
A more general solution is to add a onGC() optional method that
gets called by the GC on collections, and tells it what's inside
the union.
Bye,

It might also be possible that this is what is actually wanted:

There is always this issue as well:
alias ListInt=Algebraic!(Tuple!(),Tuple!(int,ListInt*));

D already has product type it is struct.
But D lacks sum type also called tagged-union.
Do you think it would be possible to add something like this to
D2 ?

Justin Whear:
In addition to the suggestions of Algebraic or Variant
elsewhere in this
thread, it's trivial to implement your own concrete tagged
unions:
struct MyTaggedUnion
{
enum Type { Int, Float, String }
Type tag;
union {
int int_;
float float_;
string
