-Style #21
-==============================
-
-Constraints:
-
-- Every single procedure and function checks the sanity of its
-  arguments and either returns something sensible when the arguments
-  are unreasonable or assigns them reasonable values
-
-- All code blocks check for possible errors and escape the block
-  when things go wrong, setting the state to something reasonable
-
-Possible names:
-
-- Constructive
-- Defensive
-- Hopeful
-- Shit happens, life goes on
