[Xotcl] Permissions framework

[Stefan Sobernig]

> Has anyone done any code or a framework for managing per-class permissions? Basically a way to do rules describing which other objects, or which roles users must have, in order to call the different methods provided by instances of the class (plus any class procs). This is kind of like an expanded approach to Java style simple permissions (private/protected/public), which of course could also be incorporated into that, if wanted.

Nope, speaking for myself, I have never done anything into this 
direction. (And never really felt the need for doing so.)

In the upcoming major release, there will be some "access properies" 
(like the UML2 private, for instance) to manipulate the publicly 
accessible signature interface of an object whereas these can then still 
be tweaked (removed or set) through a lower-level API at any time).
