Just FYI, I suggest usingTry::Tiny instead of plain eval.

What is the right way to see if an object has certain attribute?
if (Moose::Util::find_meta($obj)->find_attribute_by_name("foo")) {
do some stuff
}
I almost never find myself wanting this, though (except when
writing MooseX
modules, and then not often), so I'm curious what you're doing that
needs it.
hdp.
In my case the access to an attribute may be attempted with a wrong
name.
I want to provide an error message more intelligent than standard
Perl carp like
Can't locate object method "foo" via package "Bar". I don't want to
put each access code into an eval ...
There is more to it in the actual project of course.
