Outer product (aka outer join) of n lists
I recently wrote a program to automatically solve a category of logic puzzles, alone the lines of 'four men walked into a bar, one who drinks Guinness never pays darts...' The objective is to find a unique combination of attributes - name, age, favorite drink, favorite pub activity etc. I decided on a brute force approach, in which I generate every combination of attributes, apply a set of rules, and then inspect for the one unique solution. My solution starts with producing a list of lists of attributes.

Test string is all UpperCase 2
There is another "All Uppercase" snippet that does two searches - one to verify that there's at least one upper case letter and one to make sure there are no lowercase letters. "---D" is "uppercase" but "---" is not. I wanted to duplicate that behavior even though it seems a bit questionable, but do it in one regex search. The underappreciated lookahead features of RegEx allow this sort of thing - scanning forward and then rescanning forward so I use that here

Active pattern for let binding inside patterns
The Let active pattern demonstrated by this snippet can be used to assign values to symbols in pattern matching. This is useful for writing complex pattern matching using match as we can handle multiple cases using a single clause.

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.

Continuation-Passing Mnemonics
Continuations provide a means whereby heap space can be traded for stack depth (heap space being generally more plentiful than stack depth). They are especially useful where tail recursion is not possible. Here are a couple of simple continuation examples that can be extended to cover more complex scenarios.
