- He has fixed many bugs in SBCL. I can't find a nice summary theme,
- though, except that appears that at least some of them come from
- going over the BUGS file to find outstanding problems to fix.
+ He has fixed many, many bugs. There's no single summary theme, but
+ he's fixed about a dozen different bugs in LOOP alone, and it appears
+ that a lot of his fixes there and elsewhere reflect systematic
+ public-spiritedness, fixing bugs as they show up in sbcl-devel or as
+ archived in the BUGS file.

+Nathan Froyd:
+ He has fixed various bugs, and also done a lot of internal
+ cleanup, not visible at the user level but important for
+ maintenance. (E.g. converting the PCL code to use LOOP instead
+ of the old weird pre-ANSI ITERATE macro so that the code can be
+ read without being an expert in ancient languages and so that
+ can delete a thousand lines of implement-ITERATE macrology.)
