MutableString vs string

Along the lines of the discussion before about raising exceptions: Is it
acceptable to return .NET strings from library methods or should we be
trying to use MutableString instances?

Good question… I’m using always MutableString inside my StringIO
implementation but I’m not sure if it’s ok…

You should return MutableStrings and also accept MutableStrings as
parameters.

Yup.

Long term, we’ve talked about some action binder magic that would
automatically convert MutableString <-> System.String for calling .NET
methods. But that’s a long way off, so use MutableStrings for now.
