Rolf,
Once the the role is applied to the PW::Base it cannot be unapplied or
replaced, it has been composed into PW::Base for good.
I think perhaps you don't want to apply PW::RoleA to PW::Base, but
perhaps move that higher up the inheritance chain so it wont conflict
with the 'PW::Site::Xy::RoleA'.
Not much more advice I can give beyond that as I am not sure what your
problem domain actually is.

Hi,
I would like to be able to replace a role in subclass :
When I have a class and a Role
package PW::Base ;
with 'PW::RoleA';
...
;
==========
package PW::RoleA;
..
after calc => sub {.. };
==========
AND and subclass of PW::Base where I want to have another calc
method,
so I have another Role for it:
package PW::Site::Xy::Base;
extends PW::Base;
with 'PW::Site::Xy::RoleA'
...
AND
PW::Site::Xy::RoleA
excludes 'PW::RoleA';
..
after calc => sub {.. };
==========
now I get the error:
The class PW::Site::Xy::Base does the excluded role 'PW::RoleA'
So what am I doing wrong ?
