My Squeak image has decided that #, (#comma) is not a valid message 
anymore. I hope that someone has an idea or a line of attack on this, as I 
would like to see the mystery solved.

   Squeakers ...  I have a problem...
        Still flying ... but I just noticed the wings are missing.

The Issue
   #, is not being considered a valid Message pattern by the Parser
       There 6 Implementations including SequenceableCollection

   I didn't touch it. No really! I was not even looking down there.

       Parser>>pattern:inContext:
           "hereType = #comma"
           "cs: 2402ColanFreeSyntax dan 4/5/2000"

     My only recent change to a Squeak class is a fix I submitted to list 
Dec 1st
         Morph>>buildDebugMenu:

     I've been working with my own subclasses mostly in Network-Kernel , 
Mysql-Driver and Morph-*

   #, was definitely working in my image prior to Dec 1st
     - prior to Dec 1st 2000
         Version stamp on one of my messages
         I was building a string with #, to send to Transcript
         Proof that #, was working on Nov 30th

     - prior to cs 2989TmfFixes-ar
         I had promoted the project with the Nov30 change to top of Changes
         Then did the upgrade that brought in 2989 and the others since then

Observations
   This seems to be only a Parser Issue and not compiled Methods
     'Print '  Nothing more expected ->, 'It' .

   Can not save any method trying to use a #, message

   The Recent Versions Browser acts different than other method browsers
     It does not complain about syntax errors, with or without diffs showing
     I have not yet tried saving a change through this browser

   Change Sorters get Very Confused displaying a method with a SyntaxError
     Must close the Change Sorter window first
     Then the SyntaxError windows

   Lotsa Senders of #, <chuckle> Lots!


ChangeSet 2989 through 3077
   I can not see any real obvious candidate as causing this.

   NewSymbolTable (3045-3051) changes seem the most ... scary.

   ParseScript (2991,3004) relate to Syntax but they seem constrained to Morph


Current plans
   I'll keep studying the ChangeList and Parser and Symbol code
   I have not yet started backing out ChangeSets
   I will start to rebuild a new 2.9a image
