=== The Bellman's rule === 001 · · "Just the place for a Snark!" the Bellman cried, 002· · · · As he landed his crew with care; 003· · Supporting each man on the top of the tide 004· · · · By a finger entwined in his hair. 005· · "Just the place for a Snark! I have said it twice: 006· · · · That alone should encourage the crew. 007· · Just the place for a Snark! I have said it thrice: 008· · · · What I tell you three times is true." === Implementation of the rule === The little Haskell program checks whether entries in a list of statements occur three times (or more). Therefore the program is a useful tool to test the truth of statements.
