Are you saying you can't return undef from BUILDARGS?

That would be nice. Unfortunately, it's a fatal exception that requires catching: 

#!/usr/bin/perl -w
use strict;

package test;
use Mouse;

sub BUILDARGS { return undef }

__PACKAGE__->meta->make_immutable();

my $eg = test->new();
print "All good!";  # nope...

BUILDARGS did not return a HASH reference at ./test.pl line 11.

..then return undef from new.

Yer not suppose to use your own "new", but I did try defining one and having it return undef. No errors, however, the object returned is still a hash ref, not undef: 

package test;
use Mouse;

sub new { return undef }

__PACKAGE__->meta->make_immutable();

my $eg = test->new();

print $eg;

[download]

test=HASH(0x2208f08)
