I apologize. Just turn off the 
#syntaxHighlightingAsYouTypeLeftArrowAssignment preference. It should be 
off by default, and will be so in next releases. BTW, next release of 
Cuis will include "configurable underscore meaning" as Andreas did 
recently for trunk, and you can always do 'StrikeFont useUnderscore', 
meaning that Cuis will fully support the use of _ as part of selectors 
or identifiers.

This was already answered by Andreas. Thanks Andreas!

I'm not a big fan of ANSI Smalltalk, but I agree that some compatibility 
with Squeak and Pharo (and perhaps other Smalltalks) is a good thing. 
What I really like is Grease, as it can be tested for compliance. If 
anybody wants to work on Grease for Cuis, I'll be happy to help and to 
consider that work an "officially supported optional package" ((c) 
Andreas), meaning that I'd run all the test before any release, and 
integrate or write any needed fixes, to ensure it works ok. Aside from 
that, feel free to raise any compatibility issues that bite you. We 
might integrate the fix in Cuis, or in an "officially supported optional 
package". The fact is that I already have some stuff for starting such 

Does this sound ok for you?
