# A call like this...

adt Foo:

  Var1:

    foo: int

    bar: string

  Var2:

    baz:  float

    quux: char

  

# ...will generate the following types:

type

  Foo = ref FooObj

  FooKind = enum

    Var1,

    Var2

  FooObj = object

    case kind: FooKind

      of Var1:

        foo: int

        bar: string

      of Var2:

        baz:  float

        quux: char

 

# and you can do this:

let abc = Foo(kind: Var1, foo: 42, bar: "ADTs are cool")

let def = Foo(kind: Var2, baz: 13.37, quux: '*')

echo abc.repr, ", ", def.repr
