I'd post if I could. Sorry, but I doesn't look possible. Too much code and no
obvious auto-reduction criteria. Maybe this will give some info:

Here is a module:
---
import document.interfaces;
import metaui.controls.panel;
import levelling.LevFileManager;

void f(Panel!IFileManager pnl1, Panel!LevFileManager pnl2)
{
    pnl1.addSubPanel(pnl2, fileMgr => cast(LevFileManager) fileMgr); // line A
    pnl2.source = null; // line B
}
---

There are other modules where these Panel!T templates are used. If line A is
commented - project builds. If not but line B is commented we get 4 error:
----------

If line B is also uncommented we get one more error:

I can also provide remote access to my PC if someone needed.
