Really the best thing to do in this case is to just have this in an easy to access library, and call it as a function and not a string method. The only alternative is to create a string subtype which has a new method-- but that would require all the strings you're using to be this subclass. E.g. you'd have to do MyString(regular_String) for each. This is really IMHO unwieldy and not really worth the effort -- just put strip_pairs into a library and call it as a function. --S
