   Yes, exactly. I'd like to write a program that will do all kind of
searches through a huge list of objects, and I need to make the program
speed- and memory-efficient. Iterating over indices seems like a good (if
not the only) approach.

   What is a "reference"? You don't mean deep object hierarchies (a.b.c.d),
do you?

           Programmers don't die, they just GOSUB without RETURN.
