Juan,

I've finally made some time to attempt to migrate from Cuis 2.0->2.3  
(yeah, I missed a couple of releases :-) and have run into some  
issues.  The main one that jumped out at me is when I filed out my  
changesets from the 2.0 image and then back in to 2.3: in many places  
(strangely, not all), underscore assignment is being used when *all*  
of my code in 2.0 used := (and when I view the code before installing  
the changeset, it indicates that := was used on the fileout)... so  
this is either a regression (I didn't have this problem loading into  
2.0) or a feature.  If it's a feature, can it be disabled?  
#allowUnderscoreAssignment is true in both versions and is the only  
pref I saw that seemed possibly related but since there was no  
difference in the setting, I didn't expect any difference in behavior.

The other things I've run into so far are problems with what appears  
to be an incomplete changeset being generated by 2.0 (specifically  
with a class that I had renamed) and a hard crash problem (i.e. the  
image literally just quits/crashes with no error) related to OpenGL/ 
FFI that I wasn't having in 2.0.  These two are more FYI at this stage  
(and if either of these problems sounds familiar, by all means please  
let me know) as I still have some investigating to do to see if there  
is something on my end that is the cause of these problems or if it's  
something I can figure out a fix for and provide to you.

Now that I've finally gotten just about all of my stuff migrated to  
Cuis, I'm going to use this migration as an opportunity to clean my  
code up a little (OK, a lot :-) so that hopefully I won't fall so far  
behind future releases and can provide more timely feedback going  
forward.

One additional item I would like to get your thoughts on is whether or  
not you think that maintaining compliance with the ANSI Smalltalk spec  
(or some other standard) where possible (i.e. it's a capability that  
is included in Cuis) is a worthwhile goal?  This seems like it might  
be helpful in trying to remain at least minimally compatible with  
packages not specifically developed for Cuis.

Thanks,
Phil
