Is there a way to make list comprehension lazy in Elixir? If not, is there a way to turn this into a Stream?
Stream
my_list = for i <- (1..1000000), j <
A comprehension is a flat map. So your code is equivalent to:
Stream.flat_map 1..1000000, fn i -> Stream.flat_map 1..1000000, fn j -> [{i, j}] end end
I have proposed a "stream for" and "parallel for" for future Elixir versions, however it is pending some other improvements to the language.
