So this will produce:
frozenset() # empty frozen set
{1} # 1 item frozen set
{1, 2} # 2 item frozen set
{} # empty dict
{1:1} # 1 item dict
{1:1, 2:2} # 2 item dict
I think this is confusing and messy, especially for new Python programmers.
If you're going to make the change, why not make things consistent:
{} # empty frozen set
{1} # 1 item frozen set
{1, 2} # 2 item frozen set
{:} # empty dict
{1:1} # 1 item dict
{1:1, 2:2} # 2 item dict
