>That fundamentally changes the readability of Squeak code and makes all

That is not an argument, one can currently write a method:

   xxxßsoOOollx0001128üäe8
	^'Unreadble'
 
and thats not readable either.

>future code written that way incompatible with other Smalltalks.

Depends on how you see it. VisualWorks and Smalltalk/MT allow
underscores in selectors as well. Havent tested VAST, Dolphin, GNU, ...

If we dont support it in Squeak we can not load code from 
Smalltalks who support it. 

What about the following:

We can make it a preference (as it is the case with underscore assignment) and set it to false by default.

So by default the image is clean and people who need it (Glorp for
instance) dont have to patch the image/class Scanner ...

>or maintain your own fork of Squeak

Believe me - there are already enough forks ;)

More opinions please! 

Thx
