This is sort of a half-way to C#'s LINQ (language integrated native query), which has proven remarkably successful. It's been integrated into Scala as well. I think that bucket of changes is worth considering, but certainly not in the scope of project Coin.

I would love list comprehensions, but only if they were amenable to using all kinds of statements there  (methods) and many comprehension statements in one list.

List input .... List out = [x + valueToAdd for x : input if x % 2 == 0; x + valueToAdd + 2 for x : input]; Possibly this could be compressed for the same list (as here) to: List out = [x + valueToAdd if x % 2 == 0, x + valueToAdd + 2 for x : in]; With only one iteration needed. Would LOVE this.
