I just started looking at Squeak and SmallTalk last night and I'm
already getting hooked! I have a best of both worlds question. The
ability to access and edit any method or abject all using SmallTalk is
great, but is there any way to restrict a program so it can only access
certain objects?
What I'm looking for is a way to allow code to be compiled and run in
Squeak, but keep that program from being able to make or save changes
to the world, access the host (Windows/Linux, etc) file system, etc.
My first impression is that this goes against the grain of Squeak's
basic architecture and premise, but I'm wondering if maybe there's some
way to set up a world inside a world or something like that. Would it
be possible to create an object that serves as a virtual world for a
program to run in? A program running in this setup could have access
to all or most of the same classes as a program in the real world, but
it could only access the virtual-world object, it's children and maybe
an explicit subset of real world objects as defined by the
virtual-world object.
Thanks!
