Yes you're right.
Also it was wrong from my side to ask to update the 'pretty-print' filter.
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.
