Close, but no cigar. A few problems:
It's restricted to global variables.
It uses the relationship between variables and their names
at run time, and I would prefer the mapping to be done at
compile time.

Same problem
Mark> I'm curious why you need this?
I want to be able to stuff an object into a larger data
structure and have that object reach out into a variable and leave a
trail of breadcrumbs.
