+This function searches through an array and rejects all elements that match
+the provided regular expression.
+
+*Examples:*
+
+ reject(['aaa','bbb','ccc','aaaddd'], 'aaa')
+
+Would return:
+
+ ['bbb','ccc']
+EOS
+
+ if (args.size != 2)
+ raise Puppet::ParseError,
+ "reject(): Wrong number of arguments given #{args.size} for 2"
+ end

+ ary = args[0]
+ pattern = Regexp.new(args[1])
+
+ ary.reject { |e| e =~ pattern }
