Hi there,
I don't have any answer to Lanzaroto to question (sorry), but I'm curious about
drieux's code. In your code, there's a package and a group of subroutines. When you
call the Foobar::foobar(), are you only doing foobar subroutine? And, do you have to
do Foobar::foobar() and not foobar() alone? Thanks.
