This is just some syntax sugar:
Since set literals will change to for example {1,2,3} from set([1,2,3]) and
set comprehensions will be specified inside {} I feel that {} will be more
naturally associated with sets than dicts (or at least as much).
What if the empty set literal is changed to {} and an empty dict literal
changed to {:}. Performing the conversion automatically wouldn't be so complex
and also un-ambiguous. The hardest thing to change would be the mentality then.
i.e:
{} ::= set([])
{1,2,3} ::= set([1,2,3])
{x for x in y} ::= set(x for x in y)
{:} ::= dict()
{a:b, h:j} is a dict since it contains colons.
I hope this isn't a stupid suggestion (I'm new here).
