Turns out that we just noticed that absence…
We have code that wraps exceptions (in our case, coming from
``MooseX::Constructor::AllErrors``) in an exception class of our own,
then catches that.
With a recent update of the ``::AllErrors`` distribution, our code
started failing, because it now calls ``die`` instead of
``meta->throw_error``, so even if we're still using an older
``Moose``, the custom error class is not used.
So now I have a few problems:
- I have to handle exceptions coming from inside ``Moose`` as well as
those coming from various ``MooseX::*`` (and these do not
necessarily inherit from ``Moose::Exception``)
- I can't keep my wrapping logic (which extracts some useful pieces
from the various exceptions) hidden away in a single place, but I
have to call it from each exception handler
Not *hard* problems, mind you, just a bit annoying. I think I'll end
up with something like::
try { whatever() }
catch {
my $wrapped = wrap_exception($_);
if ($wrapped) { whatever_was_there_already }
else { die $_ }
};
My main issue is that I can't find any mention of the removal of
``error_class`` in any changelog or delta document…
Anyway, suggestions on how to make the above code better are welcome,
and I volunteer to help re-design / re-implement the removed feature.

One does not thank logic.
