Consider the whole combination space of bool s (which is defined as n^n where n is the size of the space) false false false true true false true true. Recall that the function not negates a boolean value. Name of your pattern = corresponding value to be executed. Is the way to build a new list from an element and another list. Web in this section, we use pattern matching to reimplement various functions in the haskell standard library. There's no general, straightforward way of matching against patterns with common variables: Web in pattern matching, we attempt to match values against patterns and, if so desired, bind variables to successful matches.
