Hi all,
I have following problem:
Base object: 
package mObject_T;
use Moose; # automatically turns on strict and warnings
has '_logicErrors' => (is => 'rw', isa => 'Str');
...

[download]
Inherited object: 
package mSomeObject_T;
extends mObject_T;
...

[download]
I need second param of some function to be inherited from mObject_T, so I check if is_a("mObject_T"): 
contract('checkName')
    ->in(is_a("mName_T"),
        is_a("mObject_T"))
    ->enable;

[download]
but contract fails, if I call function with inherited object: 
my $obj = new mSomeObject_T;
checkName($nameObj, $obj);

[download]
as is_a() gets 'mSomeObject_T' instead of 'mObject_T'. How to do it properly?

Thanks for any help.
