Interestingly, the non-dict versions can all be written today using a double-nested comprehension, e.g. {**x for x in it} can be written as:{x for x in xs for xs in it}
{x for xs in it for x in xs}
But it's not so straightforward for dict comprehensions -- you'd have to switch to calling dict(): dict(x for x in xs for xs in it)
{k: v for xs in it for k, v in xs.items()}
So actually this is just a syntax sugar.
