It=92s a quick heuristic. Speed is important for tracking down such =
things, perfection is not. Reliability is more the domain of DRC, which =
definitely needs work, and I=92ve been working on it.

Show me a drawing of a circuit you can not represent in gschem because =
of this problem. On the other hand, the majority of the board designs in =
my most recent project would be impossible in pcb, either because they =
need buried vias or different stackups in different parts of a =
rigid/flex board.
