Greetings! We've been working to add pattern guards to the Haskell' report, and doing some cleanup work on the repository. Not all of the emails are making it to the list, sadly, but here's a list of recent changes from the report. You can view the report itself here (I couldn't think of a good place to put it): http://hackage.haskell.org/~ijones/haskell-prime-report/report/haskell98-rep... peace, isaac Fri Jan 12 16:32:28 PST 2007 iavor.diatchki@gmail.com * moved rules for guards in a separate figure because the old figure didn't fit on a page Fri Jan 12 16:21:46 PST 2007 iavor.diatchki@gmail.com * fixed rule (g) of pattern semantics to avoid duplicating the evaluation of e' Fri Jan 12 16:13:50 PST 2007 iavor.diatchki@gmail.com * added rules for pattern guards to the formal semantics of case Fri Jan 12 14:53:30 PST 2007 iavor.diatchki@gmail.com * gneralized function bindings to support pattern guards, not just boolean guards Thu Jan 11 16:59:30 PST 2007 ijones@syntaxpolice.org * reworking the informal explanation of pattern gaurds Modified the syntax again to talk about "guards" (which are pattern guards, boolean guards, and let expressions) . Moved the "Pattern guards" section I created before into the Case Expressions section. Thu Jan 11 15:51:14 PST 2007 ijones@syntaxpolice.org * update pattern binding translation for pattern guards (with Iavor's help!) Mon Jan 8 10:21:14 PST 2007 Andres Loeh * turn macro into function -- makes it work with newer flex versions Mon Jan 8 09:50:40 PST 2007 Andres Loeh * don't include extension in \includegraphics (to make compatible with pdflatex) Mon Jan 8 09:20:29 PST 2007 Andres Loeh * typo: change \r to \tr
