Python 3.0 has set literals {1,2,3} (perhaps they become frozensets  
instead). But {} still is, and will be, an empty dict.
In reply to the n-th proposal to define a literal for empty sets, Guido  
van Rossum said, in python-ideas:

	"All possible proposals have already been discussed at length. Really,  
writing set() isn't so bad. Get used to it."
