In all my time I've been programming in Smalltalk (since about 2000), the
idea that Sets simply do not contain nil was a core assumption of using
collection classes for me, not just an implementation detail. I routinely
do "something asSet" to get rid of nils, and this change would break all
my code.
Now, I obvioulsy do not see the value of allowing Sets to contain nil, but
other people do. How about creating a new class to handle this? NilSet or
whatever
