Thanks, I have started looking at Attribute::Handlers myself in the meantime. It does look a little scary inside, but I guess that cannot be avoided when dealing with attributes, and as you say, with its centralized handler that just dispatches to the actual attribute handlers it is quite interoperable when many modules try to register attributes.

Since this is for CGI::Application, it would have to play nice with mod_perl, though ... (I have recently even had a bug report from someone using Apache::Reload, which makes things even more tricky)

Just make sure your handlers all run in the BEGIN phase. That will limit some of what you can do with them -- for example, you can get the name of a subroutine, but the code reference won't yet be defined. But that's no different than writing your own attribute handling code, so you've probably already dealt with it.
