If the pretty-print filter works fine for the moment, by displaying := as a left-arrow, then that's a good solution, to use := and at the same time use Smalltalk style left-arrows for assignments. So I don't really ask for an update of the pretty-print filter, but if somebody would implement it, then that's also fine of course. As you wrote, you're open to a patch if somebody would develop it, but it would perhaps be non-trivial to do it. Because I'm happy with simply _ (underscore) and I use a font that displays the underscore as a left-arrow , there's no problem. Note that there are several fonts around on the internet that display a left-arrow at the position that the current underscore is. Smalltalk is a relatively "old" language. What I like about GNU Smalltalk is that it tries to run Smalltalk in UNIX, while still retaining compatibility with the blue book. If I understand correctly the origins of Smalltalk are NOT on UNIX. But GNU Smalltalk certainly is a UNIX-oriented implementation, as far as I can see. Regards, David Stes
