Indeed, and it's very useful, although I've hit a few problems when
I changed the shape of the enclosing polygon and the hole intersected
the new polygon boundary (if I remember correctly).

Getting rid of a hole also seems (seemed?) pretty difficult. I remember simply
editing the .pcb file to remove all holes in a polygon before starting
again placing holes from scratch.
