As a clarification, if you write
use Attribute::Handlers; sub TRACE :ATTR(CODE) { ... }

Then your sub TRACE will be called once if you write

sub mysub :TRACE { }

but it will not be called for each call of mysub.

So to achieve what you want, you have to write your TRACE function in a way that, if the appropriate configuration option is set, it wraps the function in a way that makes the tracing happen. Maybe Hook::LexWrap can be helpful for that purpose.

    Corion had a meeting with some startup today. They have a very interesting DB proxy product, but their tech stack is really, really weird. They use the Pg wire protocol but not the Pg libraries to handle it. They support Pg SQL syntax, but don't use ...
    [Corion]: ... the Pg parser (or so they claim).
    [Corion]: Also, they rolled their own user management instead of supporting LDAP for user/role management, but that just shows that they're new in the enterprise market :)
    Corion also just now realizes they didn't leave business cards.
    [erix]: can you drop a name? :)
