The Haskell const function
The const function is simple, but you can use it to make your code more legible. In this example we convert a unary function to a function of arity 2 (that ignores the second argument). Also by using the flip function from Haskell (which is equally easy to define) you can ignore the first argument.

Asynchronous sequences
An asynchronous sequence is similar to the seq
109 people like thistype, but the elements of the sequence are generated asynchronously without blocking the caller as in Async . This snippet declares asynchronous sequence and uses it to compare two files in 1k blocks.

Break sequence into n-element subsequences
I'm working on parallel computations and I thought it would be useful to break work into chunks, especially when processing each element asynchronously is too expensive. The neat thing is that this function is general even though motivation for it is specific. Another neat thing is that this is true lazy sequence unlike what you'd get if you used Seq.groupBy. There are three versions for your enjoyment.
