bf6fa6b3 57=head1 DESCRIPTION
58
59This class implements L<Carp> based error generation.
60
1b27b2a6 61The default behavior is like L<Moose::Error::Confess>. To override this to
62default to L<Moose::Error::Croak>'s behaviour on a system wide basis, set the
63MOOSE_ERROR_STYLE environment variable to C<croak>. The use of this
64environment variable is considered experimental, and may change in a future
65release.
