// Thing[A] is like a simplest posssible container for a value and the
// pattern, given a Thing[A], and a function flatMap, pulls a value of
// type A out of the Thing[A] and applies the function flatMap() on this
// value of type A and returns another new Thing[B] with a value of
// type B injected into it by the constructor (apply() method here)
// encapsulates a monad in loose sense
