Jenda,

    Unrelated note: drop the &. It's not necessary in this case and means something else than people tend to think in other cases.

Could you explain this or give a reference. I see this comment a lot, and have never experienced any side-effect of using the '&'. I use the '&' to visually distinguish between in-script 'sub's and 'sub's that I have no control over via use/require/Begin.

When you haven't looked at code in 2-5 years and now need to modify it, small visual aids do help!

Thank you

    It's the old Perl4-style sub call syntax, and means "ignore prototype" and (if no arguments are passed), "make current @_ visible to subroutine" (perlsub)

    Its use is discouraged but it doesn't seem to be harmful. Personally, I just view it as ugly and a hint that "this user learned Perl from tutorials written in 1995"

      AM,

      And if the user started using Perl in 1996, then I would expect that to be true!

      The prototypes are fine, it's the "current @_" that I meant. There's a big and likely hard to debug difference between &foo(); and &foo;.

      Jenda
