Re: Problems with SRFI document

[Andre van Tonder <andre@xxxxxxxxxxxxxxxxx>]

Hello Michael,

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).

Regards
Andre
