I asked around a little where I work (corporate type environment). In
general, the impression was that either developers don't know about
Set, or can't be bothered using them as List will do. Being
comfortable with List (and thus not having to think about another
type) was a factor.
One point I keep on making is that those of us here on this mailing
list, or reading any kind of blog, are completely atypical of the vast
bulk of developers. When taking decisions we have to be mindful of
that, as in essence its very hard to hear the view of the famed
The question here seems simple - whether having a Set literal in the
language would encourage more usage of sets. Based on what I've seen,
I'd say thats marginal.

puzzler. To me, that strongly suggests omitting set literals,
hopefully in favour of ListLiteral.toSet().
