A little more:
i want this because then i can use <handler name="onmyevent"
reference="parent"> without the SWF9 stricter constraint system crashing
on me. the attribute would not exist at the time the handler was
evaluated so it would fail (fine) but new objects made in the system
could see it, and that would lead to being able to write code that uses
handler tags.
My guess is i'm seeing just a small issue in the constraint system that
will get sorted out soon.

You can do this in on operation:
new lz.Delegate(this, 'something', that, 'eventname');
you'll want to hang on to a reference to the new delegate, so you can
unregister it in your destroy method, otherwise it causes a leak.
We hope to fix this some day:
http://jira.openlaszlo.org/jira/browse/LPP-225
Also, we have some ideas about how to dynamically add handlers, so
that you don't have to understand the delegate mechanism to do what
you want. (Hm. can't find the Jira for tha just now...)

Poor form, sorry, but i answered my own question. I didn't need to
do make another attribute. i found another way around the problem
using these two lines which are a common pattern:
var something_method = new lz.Delegate(this, "something");
something_method.register(parent.after, "onmyevent");
That worked just fine for my needs once i realized it was all i
needed. Thanks for reading it!
