Maybe we cannot blame the underrepresentation of Scheme for this, but
I would have thought that everyone pulling in the sample
implementation and stumbling upon this would have reported it... But
you are actually right; I just found this comment in Larceny's

(Maybe someone should check the other comments there as well.)
