I am -0 on set syntax support. If the set() constructor was expanded
to take an arbitrary number of arguments (and thus be more inline with
the dict constructor) then the syntax need really starts to go away
since the above could be done as ``set(1, 2, 3, 4, 5)``.
As for the set copmrehension/expression/thing, I don't think that is
needed at all when ``set(z for z in x if z % 2)`` will get the job
done just as well without adding more syntactic sugar to the language
for something that is so easy to do already.
