a hash literal works like this, index with the typeid to get a function
ptr you can call:
Algebraic!(int, Foo) a;
a = 3;
[ typeid(int) : function { writeln(a is int); },
typeid(Foo) : function { writeln(a is Foo); }
] [a.type] ();

Oh, that makes sense, but I don't see why you need language support for
that, a variant type should be able to get most of it using type tuples,
maybe just add support to switch on type tuples along with an opSwitch()

Exactly, this is what I mentioned previously. Isn't it ugly compared to
type Event = Mouse | Key | Move;
void dispatchEvent(Event event) {
match(event) {
Mouse m = m.squeek();
Key k = ...
...
}
}
What's with all the language proposals here? Why

One way or another you will, and if you have difficulties let us hear of
them. Practical experience with Algebraic and friends is very valuable.
