Thanks! I actually figured this out and now have 
do "my_module.pm";

[download]
instead of 
use my_module;

[download]
I think that does the clobber of %INC and forces the reload. My guess is that this differs from eval "$source" solution you mention only in that I'm actually reading the module from disk each time with the "do" solution.
