For Mouse this monkeypatching would work:
diff --git a/xs-src/MouseUtil.xs b/xs-src/MouseUtil.xs

Followed by:

use Carp;
sub Mouse::Util::throw_error :method {
my($self, $message, %args) = @_;
local $Carp::CarpLevel = $Carp::CarpLevel + 1 + ($args{depth} || 0);
local $Carp::MaxArgNums = 20; # default is 8, usually we use

}
}
package Foo;
use Mouse;
has x => (is => "ro", isa => "Int");
my $foo = Foo->new(x => "blah");
use Data::Dumper;
print Dumper $foo;
Which'll give you:
$ perl -Mblib -Ilib /tmp/error.pl
