role stub workaround fails for parameterized roles

There is a problem described for roles, where an attribute defined by one role is used in another.  The workaround given is to have the parent define a stub method with "sub METHOD {}"


This doesn't work for MooseX::Role::Parameterized roles.  In this case, even

with the stub declred, there is still the error:  Attribute (ATTR) of class CLASS has no associated methods (did you mean to provide an "is" argument?)


I presume that this is related to the requirement in parameterized roles that method cannot be declare as sub's but must be declared using the "method" keyword.


Is there a way to declare a stub  method for parameterized roles?
