Re: Problems with SRFI document
Just a couple of comments on the fix:
1) The stream-low-level-lazy, ...strict, ...delay and ...force
implementations have a pretty serious bug. This bug was discovered by
Alexandro Forero Cuervo and discussed on the SRFI-45
list (with some spillover to the SRFI-40 list). I posted a
fix - please see the patched SRFI-45 document for the details.
(also, AFC posted a patched version of SRFI-40 incorporating
a version of the fix to this list).
2) I believe the discussion of stream-unfoldn in the first
part of the implementation section was obsoleted by the
SRFI-45-style promises (indeed, the actual implementation
below it was then changed back to using the naive
version, which should be correct and safe for space).

Good points, both. Fixed. Thanks for the note!
