MooseX::SemiAffordanceAccessor is a module that changes the default naming policy for the loading class so that methods are separated into accessors (which have the same name as the attribute) and mutators (via set_ methods). . It is compatible with existing naming schemes, since attributes that explictly provide a "reader" or "writer" name are left unchanged. The terminology "semi-affordance" is inspired by David Wheeler's Class::Meta module (see libclass-meta-perl).
