Thank you for your opinion on this. Regarding the "if" part, there are
two parts: the canonical Dylan linearization, upon which the paper
(mentioned in my original message) is improving and the actual
improvement. The code above corresponds to the improvement. My patch
also has parts derived from the unchanged parts of the canonical
implementation.

I thought the part derived from the canonical implementation should not
be a problem since the canonical implementation is available under GPL
in Open Dylan.

Thanks again,
Jan
