I'm sorry I forgot to mention that ALL function calls go through this universal autoloader, and if the function can not be found in the symbol table it figures out the package name with a regular expression, requires the package, and then calls the function: 
# figure out package name as $pkg
eval "require $pkg;";

The real problem is similar to a dynamic plugin system, but I do not want the residual effects of loading a package (permanently modifying the symbol table) that exists elsewhere.
