This is interesting... I'm a Pascal oldtimer myself,
and I can understand the motivation for this.

However, it's not obvious to me there's a way to
do it in Ruby.

There are future plans for a way to "hook" into the
entry and exit of a method, if I understand correctly...
that might be a useful line of research for a future
way to do this... that's assuming the reflection API
has a way to retrieve local vars for a method, which
I can't recall at the moment.

Sorry no help.
