Subject: croak reports in the context of Class::Std instead of caller
Calling croak inside a BUILD block reports the error at Class:std line 438 instead of the line from the calling package. use Class::Std { my (%file_of,) :ATTRS; sub BUILD { my ($self, $oid, $arg_ref) = @_; $file_of{$oid} = $arg_ref{file} or croak "Missing initializer"; } } This is a very simple example and init_arg would work but croaking on more complex initialization yields difficult to trace error messages. Perl v. 5.8.7 Carp v. 1.0.4 FreeBSD 6.0-STABLE

FWIW, I get around this for now with: our @CARP_NOT = qw( Class::Std );

-- Thanks for the tip. I'll give it a try.

Class::Std *is* calling BUILD so if you croak and want ot to come from where new() is being called you need to: sub BUILD { local $Carp::CarpLevel = $Carp::CarpLevel + 1; ... carp 'whatever' if $whatever; } Perhaps we can add this automatically or shall it stay as part of due diligence?

This is something I should have caught. It makes sense. I suggest it should be added automatically because that is the expected behavior. Either way, it should be documented in the POD. Thank you for clearing this up. --
