this is great news, thanks a lot for this effort. I will update the
web-site of Pier.
FYI: I also forwarded your mail to seaside at lists.squeakfoundation.org
(the Seaside mailing list) and smallwiki at iam.unibe.ch (the
Magritte/Pier mailing list).

Please give me a list of methods that rely on Set/Dictionary equality,
so that I can fix the code in Magritte/Pier. I guess it would be
easier to make the code more portable than having the porters to patch

Indeed, a well known problem, that should be easily fixable in Squeak
as well. I assume that I can find all the occurrences of this problem
by looking at the senders of #sort: ?

Mhh, another thing I should know. I will fix it as well.
