Now the original code compiles with no errors. But if I try to to instantiate a
Foo that contains an array of Foos:


import std.variant: Algebraic, This;
import std.typecons: Tuple;
alias Foo = Algebraic!(int, Tuple!(This[]));
void main() {
    auto f = Foo(0);
    auto f = Foo([Foo(0)]);
}


I see (dmd 2.065alpha):

...\dmd2\src\phobos\std\variant.d(548): Error: static assert  "Cannot store a
VariantN!(8u, int, Tuple!(This[]))[] in a VariantN!(8u, int, Tuple!(This[]))"
temp.d(6):        instantiated from here: __ctor!(VariantN!(8u, int,
Tuple!(This[]))[])
