Perl subroutines

[Paul Mooring]

I didn't necessarily mean that was a bad way to do it, just that I
prefer other methods, but I suppose that's more my problem than
perl's, for example I have a few ruby scripts that need to use
openstruct, define a new object and pass that in to make command line
options work.  Perl doesn't need any of that @_ already is essentially
what an openstruct object is trying to accomplish without any extra
code, and in that regards I can appreciate that some people like that,
but that's not how my mind works.
