Subject: Stack Frames, Functions and Variables.


I have a number of questions:

1. Is it possible to examine current stack frame in ruby. Or move up in
the stack frame to find the local variables of the function that called
you?

2. Can I put a hook that gets called whenever anyone or anything accesses
a function AND/OR a variable within an object? I would like to intercept
that call to create a nice wrapper.

3. This should be a really easy question to answer:

   Class Foo
	@test = "Hello World"
   end

   Class Bar
	@test = Foo.new

	def bar
		puts @test.@test (???)
	end
   end

How do I access a local variable of an object pointed to as local
variable. Is is a scoping problem? Are they just not visible? Should I
make them public? Should I stand on a crossroads at midnight swinging a
black cat in a circle thirteen times?

Please help.
