Hmmmm...
I haven't used the trace keyword much, so I don't know.

I should probably also mention that I believe the trace
method requires that the line vector points towards the
plane. (Please correct me if I'm wrong about this.)

While one can overcome this problem with some vector
calculations, I'm quite sure that the parsing time for
this will be longer than for the expression I suggested.
