-# Case Statements
-
-Nimrod also supports case statements, which are like switches in other languages. There are several things to note here:
-
-* You can use strings in the switch statement
-* Sets and ranges of ordinal types are also usable
-* case statements, like most things, are actually expressions
-* It is required that every possible case be covered

-case "charlie"
-of "alfa":
-  echo "A"
-of "bravo":
-  echo "B"
-of "charlie":
-  echo "C"
-else:
-  echo "Unrecognized letter"
-
-case 'h':
-of 'a', 'e', 'i', 'o', 'u':
-  echo "Vowel"
-of '\127'..'\255':
-  echo "Maybe, but I only know English"
-else:
-  echo "Consonant"
