Re^2: How Are Attributes Useful?

Zaxo,
Reflect that that attribute is more than a tag that you may query at runtime like some kind of metadata. I'm not sure how I'd go about querying that.

Really. I haven't found a single example of how one might modify the behavior of a subroutine using attributes outside the few built-ins. As far as querying the attributes - it was in the synopsis of perldoc attributes

use attributes ();    # optional, to get subroutine declarations
my @attrlist = attributes::get(\&foo);

I have looked at Attribute::Handlers and still felt unsatisfied. Attribute::Handlers::Prospective looks promising after glancing at the documentation but I find it hard to believe that there are no code examples outside the module. Why is this I wonder. It seems to me that you are right - the majority of us are in the dark and so attributes, if useful at all as others have implied, are way underdeveloped in perl.

Cheers - L~R

Check Bot-CPAN. It's Glue module uses Attribute::Handlers to define well.. attributes to methods. That lets you define a bot command like: `sub list :help ("lists available modules") :private :adminCmd { # implements list() }` [download] I thought that was a rather elegant way of doing this.
