When displaying data about a variable, does it volunteer variable names or does it just respond with a value?
I would be very disappointed to find out it did
The debugger is exposing nothing new here, the same thing could be done anyway through any of the SU consoles by any savvy Rubyist - using nothing but standard Kernel method calls. Setting trace functions and using the returned bindings to read local and instance variables, get the current method and its call signature, read the call stack etc... can all be done from even the most basic install of Ruby.
You can't actually read the code lines unless they are in a 'plain text' source file (the scrambler presumably 'evals' the unscrambled code, which precludes seeing the source) - but there's not much that can be done to secure the other information without losing the consoles - which would make life very difficult for the amateur developers that we all rely on for our toys!
