list comprehensions.md

these are all pretty similar --

Scala:

val outer = List(List(1, 2, 3, 4, 5), List(4, 5, 6, 7, 8))
for {
  inner <- outer
  x <- inner
} yield x

Python:

outer = [[1, 2, 3, 4, 5], [4, 5, 6, 7, 8]]
[x for inner in outer for x in inner]

Haskell:

outer = [[1, 2, 3, 4, 5], [4, 5, 6, 7, 8]]
[x | inner <- outer, x <- inner]

-- so why does python's syntax feel so uniquely backwards to me?
