Sure, but can you give examples where you can't use lambda, but still want it to have no name? Then show what your proposed syntax is, and how it would improve the code. Side point: I hardly ever use map with lambda functions in Python. I'll use map with an existing function (eg "map(int, list_of_strings)" to intify everything), but otherwise, I'll use a comprehension. Comprehensions are also restricted to expressions only, but your proposal won't help them.
