Spoke too soon! Now I'm seeing a brand new problem. My custom base class uses
Moose directly (not my Biome sugar class) to avoid recursive inheritance. This
gives the base class a default error metaclass of Moose::Error::Default. If I
do something like the following bit of code, it fails indicating the error
metaclass doesn't match:
# Tried to use 'Biome::Tools::IUPAC'.
# Error: The error metaclass for Biome::Tools::IUPAC (Biome::Root::Error)
is not compatible with the error metaclass of its superclass, Biome::Root
(Moose::Error::Default) at
/opt/perl512/lib/site_perl/5.12.1/darwin-thread-multi-2level/Class/MOP/Class.pm
line 277
--------------------------
package Biome::Tools::IUPAC;
use Biome;
no Biome;
1;
--------------------------
Oddly enough, if the above also consumes a role it appears to work just fine.
I would assume one way to work around this is to add the error metaclass
explicitly in the base class:
__PACKAGE__->meta->error_class('Biome::Root::Exception')
but attempting to do so doesn't work, either; in fact, the error oddly inverts:
# Tried to use 'Biome::Tools::IUPAC'.
# Error: The error metaclass for Biome::Tools::IUPAC
(Moose::Error::Default) is not compatible with the error metaclass of its
superclass, Biome::Root (Biome::Root::Error) at
/opt/perl512/lib/site_perl/5.12.1/darwin-thread-multi-2level/Class/MOP/Class.pm
line 277
Any ideas? Again, just turning off custom error classes works, but it would be
nice to have this working.
