[Python-ideas] Possible method of distinguishing between set-literals, dict-literals, and odict-literals

[Bruce Leban]

Personally, if I had a time machine I would pick a syntax like
        set{...}
over
        set([...])
but I don't have a time machine and even if I did I don't think I'd use it
for that. The difference is that the former is special syntax, while the
latter isn't. No matter what I do to the the varible r, r"string" is still a
string, while set([...]) can be perverted.

However, given what we've got I can't really say that ([ instead of { is
that big a deal.
