this show the invariant problem

The code example below is a cut down version of a larger code.

The code was written for in D1 and is now converted to D2.

In D1 the invariant test passed but in D2 it does not DMD 2.060 2.061 2.062.

The problem occurs in the this() member of Plane. 
In line 293 of test_painter.d the pl_bottom private member function is
initialized and it fails in the invariant line 336.

A debugger (gdb) show that the invariant function is called even when a private
member is initialized.

Maybe invariant function has changed meaning in D2 but then I don't know how to
use invariant in D2.

I have tried to put the private keyword in front of the invariant but it
doesn't seem to have any effect on the invariant.

I except that invariant is like unittest so they a kind of private

Thank you for the good work you are doing.
