crash course in stream/monadic style haskell/scala/f# etc?

[Raoul Duke]

something online recommended? like, how are things like LINQ done? i
find myself writing loops that are looking through what is a lame
database, and i want to e.g. early abort the loop as soon as it knows
it shouldn't bother going any further, but the C style break statement
isn't enough in these nested call stacks ;-)

Iteratees, maybe?

The Play framework has an approachable tutorial + implementation:

The pipes [1] library in Haskell is exploring a solution to this problem. It is still in progress but I've found the documentation [2] very readable.
