in reply to Core module: Attribute::Handlers behaviour

use constant, don't use attributes to control tracing

Also, post an example of what you're talking about

    Thanks for quick response.

    In my openion use constant; is a good solution for debug/info/error msgs. But if we are talking about tracing ...

    it is like in log file ...

    [<date_time>] TRACE: entering sub for ... [<date_time>] TRACE: parameters passed ... [<date_time>] TRACE: exiting sub for ...

    as core module add attribute features during compilation only, there is less performance issue...less cluttering in your code. as compared to explicitly writing entry/exit for each module.

      Sounds like a cool and effective use of attributes to me. But still, you are more likely to get help with the problem if you supply code people can try.
