[;1m  get(Key)[0m

  Returns the value [;;4mVal[0m associated with [;;4mKey[0m in the process
  dictionary, or [;;4mundefined[0m if [;;4mKey[0m does not exist.

  The expected time complexity for the current implementation of
  this function is O([;;4m1[0m) and the worst case time complexity is O([;;4mN[0m
  ), where [;;4mN[0m is the number of items in the process dictionary.

  For example:

    > put(key1, merry),
    put(key2, lambs),
    put({any, [valid, term]}, {are, playing}),
    get({any, [valid, term]}).
    {are,playing}
