+  newfunction(:delete_regex, :type => :rvalue, :doc => <<-DOC
+    deletes all instances of a given element that match a regular expression
+    from an array or key from a hash. Multiple regular expressions are assumed
+    to be matched as an OR.
+
+    *Examples:*
+
+        delete_regex(['a','b','c','b'], 'b')
+        Would return: ['a','c']
+
+        delete_regex(['a','b','c','b'], ['b', 'c'])
+        Would return: ['a']
 
-*Examples:*
+        delete_regex({'a'=>1,'b'=>2,'c'=>3}, 'b')
+        Would return: {'a'=>1,'c'=>3}
 
-    delete_regex(['a','b','c','b'], 'b')
-    Would return: ['a','c']
+        delete_regex({'a'=>1,'b'=>2,'c'=>3}, '^a$')
+        Would return: {'b'=>2,'c'=>3}
 
-    delete_regex(['a','b','c','b'], ['b', 'c'])
-    Would return: ['a']
+     Note that since Puppet 4 this can be done in general with the filter function:
 
-    delete_regex({'a'=>1,'b'=>2,'c'=>3}, 'b')
-    Would return: {'a'=>1,'c'=>3}
+        ["aaa", "aba", "aca"].filter |$val| { $val !~ /b/ }
+        # Would return: ['aaa', 'aca']
 
-    delete_regex({'a'=>1,'b'=>2,'c'=>3}, '^a$')
-    Would return: {'b'=>2,'c'=>3}
