I totally agree! Using 'isa' pulls in the type checker. Do we have the
same option for 'does' e.g. 'doesa'? Or is type checking always
implied
in role composition? Note that the class can override a role's methods
at will.
It occurs to me that this shouldn't be new keywords, but adverbs, i.e.
``is :strict Dog''.
