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.
