in reply to How Are Attributes Useful?

IIRC, Maypole makes use of subroutine attributes to check whether some subroutines are "exported" or not. Rather than having to maintain a list of "exported" subroutines, you simply add the "exported" attribute to the subroutine and Maypole will do the right thing (or so the docs say -- unfortunately I have not been able to get Maypole running on my system).

    CountZero,
    This was an example tye provided in the CB where the same thing could be accomplished without attributes. Like I said, it is nice that it makes certain very specific tasks easier but it seems that there should be something more general and more powerful about them. I haven't had a chance to go through all of the replies yet so hopefully someone has demystified it for me/us.

    Cheers - L~R
