I zealously refactored #selectors also, and that is controversial, see

http://lists.squeakfoundation.org/pipermail/squeak-dev/2009-October/140383.html

In the interim put asSet in #selectors or in Seaside.

Anyway, there should be a place where to put release notes, expecially
when a change might break some compatibility.
