I actually didn't meant it was a bug :) I need to be sharper with
my english... I meant raising an error message if self == aCollection
... Could it be a fix ?

Because in a way, the behavior is not really an error, it's more a bad
use because we know it's iterative and then, self and aCollection
change in the same time...

I hope you don't take my remarks, as "I want to change smalltalk"... I
just want to understand it better ;)

ps: by the way, I'll open a bug report, as finally I think it's an
error (arf....) because I shouldn't be aware removeAll is
iterative....etc... so here is the bug report
(http://bugs.squeak.org/view.php?id=6937).
