The default behavior is like L<Moose::Error::Confess>. To override this to default to L<Moose::Error::Croak>'s behaviour on a system wide basis, set the MOOSE_ERROR_STYLE environment variable to C<croak>. The use of this environment variable is considered experimental, and may change in a future release. =head1 METHODS =over 4 =item B<< Moose::Error::Default->new(@args) >> Create a new error.
