I think this could be done relatively easily in a sub-class using
filter and an overridden param().  Here's how:

  - Your custom filter parses the SCOPEs and find VARs inside them.
    It alters their names to include the SCOPE name.  For example, a
    var named "foo" inside a scope called "bar" might be "foo...bar".

  - Your custom param() looks for hash-refs and similarly modifies
    their names into "scope...var" format.

  - For extra credit, catch exceptions and fix the names so they don't
    expose the grotty internals to the end user.
