           /mo'nad/ A technique from
          category theory which has been adopted as a way of dealing
          with state in functional programming languages in such a
          way that the details of the state are hidden or abstracted out
          of code that merely passes it on unchanged.
          A monad has three components: a means of augmenting an
          existing type, a means of creating a default value of this new
          type from a value of the original type, and a replacement for
          the basic application operator for the old type that works
          with the new type.
          The alternative to passing state via a monad is to add an
          extra argument and return value to many functions which have
          no interest in that state.  Monads can encapsulate state, side
          effects, exception handling, global data, etc. in a purely
          lazily functional way.
          A monad can be expressed as the triple, (M, unitM, bindM)
          where M is a function on types and (using Haskell notaion):
          	unitM :: a -> M a
          	bindM :: M a -> (a -> M b) -> M b
          I.e. unitM converts an ordinary value of type a in to monadic
          form and bindM applies a function to a monadic value after
          de-monadising it.  E.g. a state transformer monad:
          	type S a = State -> (a, State)
          	unitS a  = \ s0 -> (a, s0)
          	m `bindS` k = \ s0 -> let (a,s1) = m s0
          			      in k a s1
          Here unitS adds some initial state to an ordinary value and
          bindS applies function k to a value m.  (`fun` is Haskell
          notation for using a function as an infix operator).  Both m
          and k take a state as input and return a new state as part of
          their output.  The construction
          	m `bindS` k
          composes these two state transformers into one while also
          passing the value of m to k.
          Monads are a powerful tool in functional programming.  If a
          program is written using a monad to pass around a variable
          (like the state in the example above) then it is easy to
          change what is passed around simply by changing the monad.
          Only the parts of the program which deal directly with the
          quantity concerned need be altered, parts which merely pass it
          on unchanged will stay the same.
          In functional programming, unitM is often called initM or
          returnM and bindM is called thenM.  A third function, mapM is
          frequently defined in terms of then and return.  This applies
          a given function to a list of monadic values, threading some
          variable (e.g. state) through the applications:
          	mapM :: (a -> M b) -> [a] -> M [b]
          	mapM f []     = returnM []
          	mapM f (x:xs) = f x		   `thenM` ( \ x2 ->
          	                mapM f xs          `thenM` ( \ xs2 ->
          	    		returnM (x2 : xs2)         ))

  MONAD, n.  The ultimate, indivisible unit of matter.  (See
  _Molecule_.)  According to Leibnitz, as nearly as he seems willing to
  be understood, the monad has body without bulk, and mind without
  manifestation -- Leibnitz knows him by the innate power of
  considering.  He has founded upon him a theory of the universe, which
  the creature bears without resentment, for the monad is a gentlmean. 
  Small as he is, the monad contains all the powers and possibilities
  needful to his evolution into a German philosopher of the first class
  -- altogether a very capable little fellow.  He is not to be
  confounded with the microbe, or bacillus; by its inability to discern
  him, a good microscope shows him to be of an entirely distinct
