Type solving not complete in mutually dependent modules

[ghost]

a.d

module a;

import b;

class Node
{
    Data d;
}

b.d

module b;

import a;

class Data
{
    Node n;
}

c.d

module c; import a, b; void main() { Node n; n.d.n. }

dcd-server -I./ &
dcd-client -c51 c.d

outputs nothing. should output class props and d.
D semantic is multi pass so this works as code but to get the completion I'd have to use an interface, like for language that don't do multi pass.

Top priority issue imho.
