should do what you want.

Note that it executes at run-time (while use executes at compile-time), but that's probably fine. Wrap the code in a BEGIN { } block if you need to execute this at compile-time.

Note that it doesn't import symbols, but that's probably a good thing for dynamically loaded modules. Add $mod->import if $mod->can('import'); if you need to import symbols.

Update: PodMaster suggested that I provide these links: use, require.
