Thank you for the patch and follow-up, Stefan!  And apologies for the late reply.  In the end I ended up committing something else, taking the implementation from http://srfi.schemers.org/srfi-1/srfi-1-reference.scm.  It too does not deal well with circular lists.  Oh well, though -- doesn't seem to be a big deal.

Cheers,

Andy

Note, the proposed code in take.scm below does not work for circular lists.

I attached a file take.scm for a proposed fix of this issue.

I Will make a few tests that verify it's functioning and post it as well. but before that I will wait for eventual comments.

SRFI-1 `drop-right' and `take-right' don't work with dotted lists (as of 1.8.4), but they should.

Original report: http://thread.gmane.org/gmane.lisp.guile.devel/7196 .
