What about a mutable struct that's immutable from the standpoint of external code?

Update: It occurred to me after posting this question that the main downside of this idea would simply be that such a type would be easy to use improperly. That is, the type would have to be used in a very specific way to draw any benefits. What I originally had in mind was something that would be used like this (sticking with the Square...

In a shell application, I need to be able to load and execute other .NET assemblies at runtime, but without giving them full trust.
