Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

1) I have a library path set up like the following at the beginning for my .pl files. If I have a module by the same name(say MyModule.pm) present in both directories, which one will perl use?

2) Also, the approach I have taken to include perl modules, is it a good one. Are there better ways?

Thanks 

BEGIN {
    unshift (@INC, "/common/LIBRARIES");
    unshift (@INC, "/common/LIBRARIES/common");
}

    1) The first one Perl finds, iterating from @INC from start to end, so /common/LIBRARIES/common/MyModule.pm

    2) Functionally perfect, so the only possible improvement is style. I'd use 

    use lib "/common/LIBRARIES/common", "/common/LIBRARIES";

    But even the following would be better to me: 

    BEGIN {
    unshift @INC, "/common/LIBRARIES/common", "/common/LIBRARIES";
}
