+  newfunction(:bool2str, :type => :rvalue, :doc => <<-DOC
+    Converts a boolean to a string using optionally supplied arguments. The
+    optional second and third arguments represent what true and false will be
+    converted to respectively. If only one argument is given, it will be
+    converted from a boolean to a string containing 'true' or 'false'.
+
+    *Examples:*
+
+    bool2str(true)                    => 'true'
+    bool2str(true, 'yes', 'no')       => 'yes'
+    bool2str(false, 't', 'f')         => 'f'
+
+    Requires a single boolean as an input.

+    value = arguments[0]
+    true_string = arguments[1] || 'true'
+    false_string = arguments[2] || 'false'
+    klass = value.class

+    # We can have either true or false, and nothing else
+    unless [FalseClass, TrueClass].include?(klass)
