I'm totally confused by your statement that the file level lexicals are "never used". They are set and read - how else can you use a variable? In any case, file level lexicals are not destroyed, except perhaps when the script ends. After my original code, I can still access and print their values. For example, in my original package TestModule, I can add these functions: 
sub get_str { return $str; }
sub get_h { return $h; }
sub get_l { return $l; }

Then, in the script, after my original code (where you claim that the variables will be destroyed before my original code printed their values), I can add this, and the correct values of the variables are output: 
print(Dumper(TestModule::get_str()));
print(Dumper(TestModule::get_h()));
print(Dumper(TestModule::get_l()));
