Re: sub running on use statement

Another possibility is that ScrewyModule.pm has a sub import() that calls other subs:

package ScrewyModule;

sub import{
    test();
}
sub test{
    print "in ScrewyModule.pm\n";
}
1;

In this case test() gets called (via import) when the module is "use"d.

Yes, that's what I have in the module. Quite a few, actually. The sub-routine that I noticed this printing on is recursive, calling itself to fill an array with all the files in a directory tree. When that recursive subroutine was called from another module, it printed when I didn't expect it. One of the scalars passed by reference to that recursive subroutine is the parent directory to search. I'd inserted a print statement just after the references were taken from "$_" to confirm that the parent directory was correct.	[reply]
