 Replying to [comment:1 felix]:
 > I don't think this is a bug, to be honest. The pattern `(x ... y)` is
 not legal in matchable, AFAIK. In fact, `a' shouldn't match at all, since
 it is not a list, not even a pair.

 That is the only way I know for matchable to match the end of a list.  How
 do you make matchable match "a list ending in x, y, and z"?  It seems like
 the ... operator is doing just that, and it that isn't legal what does one
 use instead?
