Has anyone suggested introducing a mutable string type (yes, of course) and distinguishing them from standard strings by the quote type - single or double? As far as I know ' and " are currently interchangeable in all circumstances (as long as they're paired) so there's no overloading to muddy the language. Of course there could be some interesting problems with current code that doesn't make a distinction, but it would be dead easy to fix...

Hi, I feel I'm going around circles on this one and would appreciate some other points of view. From a design / encapsulation point of view, what's the best practise for returning a private List<as a property. Consider the example below, the class "ListTest" contains a private "List<>" called "strings" - it also provides a public method to add to that list,
