No it hasn't. Please throw away your preconceptions and report the actual
problem.

You mean you added 'use Moose' somewhere and thereby found you had a 'with'
sub imported. That happens when you add import lines.
You can ask Moose to not import with, you can ask Error to not import with,
or you can ask Moose to import with under a different name.
But I don't even understand why you added 'use Moose' to your own classes at
all since that's in no way required to use Catalyst 5.80 - we spent a lot of
time making sure old code Just Worked for every application we could get at.

is the BEGIN block -before- the 'use Catalyst' line?

I have no idea how it doesn't work yet because you didn't tell us what didn't
work.
Maybe you could elaborate a little?

Which is a warning, not an error - though it's a little annoying. Let's fix
everything else and get to that one last?

I can't find Error::Throws on CPAN.
Is it a private package?
If so, please show us what it contains - we're not really going to be able
to debug it otherwise.

I have no idea what you mean by "hit Moose" and I have no idea how Moose
and Embperl are remotely related. Could you elaborate please?

Not until you tell us what the actual problems are, no, sorry.

Erm, that'll only break things if you import the Moose helper
functions into the same package as you try with Error.pm.
You don't have to have a 'use Moose' in your package to use new
Catalyst - so everything should just work (i.e. I don't see why you're
crashing into this unless you're changing your application).
If you do want/need this to work, then just do something like this:
package Foo;
use Moose;
# Moose attribute and role declearations here
no Moose;
use Error :try; # Or whatever you're doing
# Put your methods here
Fortunately I didn't use "with", and could just comment it out. But
what I did have was my own Error subclass that was the Catalyst
Exception class.
BEGIN {
$Catalyst::Exception::CATALYST_EXCEPTION_CLASS = 'Error::Throws';
};
I have no idea how to even get started on making that work. I made
Error a Moose inherited module from Catalyst::Exception (which is
the wrong level, but it got rid of:
Not inlining 'new' for Catalyst::Exception since it is not
inheriting the default Moose::Object::new
If you are certain you don't need to inline your constructor,
specify inline_constructor => 0 in your call to Catalyst::Exception-

Erm, this is a warning and shouldn't cause any issues.
But then that left me with
Recursive inheritance detected while looking for method 'isa' in
package 'Catalyst::Exception' at /usr/local/lib/perl/5.8.8/Class/MOP/
Class.pm line 570.
If someone has a quick way of telling me how to make my code
compatible with Catalyst::Exception that would be great, but I'm
worried that I'm going to hit lots of other things like this.
More recent Catalyst releases have changed the way exceptions are
handled to be more compatible with people overriding things, however
as you haven't really given us any details (like what your
'Error::Throws' class actually is / what it contains), or what the
error actually is if you try and use it unmodified - so I can't really
speculate..
In particular, I'm also using Embperl as a Catalyst interpreter
instead of TT,
Erm, you means as the view? Surely perl is the interpreter here
Any suggestion on a solution that isn't going to take me days?
Yes, give us some actual details about the issue you have :)
FWIW, most people's applications run entirely unmodified with Catalyst
5.80, and I'd very much guess that exception handling is likely to be
the only major issue you have...
The above proves that you're changing your app before actually just
trying to get it running - which is causing you more problems than
it's solving!
Cheers

[Catalyst] Pre-Moose version of Catalyst and all plugins?
I'm trying to get some old code running in a hurry. Unfortunately Moose has
completely fouled things up.First it broke my use of Error.pm (conflict with
