/**
 * The CaseFunction takes two arguments and returns two arguments.
 *
 * CaseFunction takes, first, an expression that yields a boolean.
 * Second it takes an expression that produces a result.
 *
 * If the first expression is true, then CaseFunction returns a list of first the true booolean and
 * then the result of the second expression's evaluation.
 *
 * If the first expression is false, then CaseFunction returns a list of first the false boolean and
 * then a null because the second expression will never be fetched, causing evaluation.
