[Scheme-reports] must list-copy handle cycles?
Per Bothner 02 Jul 2012 20:28 UTC
The text for list-copy seems to suggest that it must handle
cyclic lists, but it doesn't explicitly say so.
The Common Lisp Hyperspec says of copy-list:
The consequences are undefined if list is a circular list.
If list-copy must handle cycles, what's a good algorithm?
