-# A mixin is realised by an otherwise ordinary class which is put in a
-# dedicated mixin relation to another object or class. Hence, we refer
-# to such classes as mixin-classes. If the mixing target is another
-# mixin-class, we refer to the source mixin-class as a transitive

-# @glossary forwarder
-#
-# A forwarder is a method-level delegation mechanism to realise a
-# variety of programming techniques (e.g., signature adapters, method
-# decorators). The forward-owning object (or class) exposes the
-# forwarder as a method (e.g., in its signature interface and through
-# method-level introspection). Delegation targets are not limited to
-# other methods, arbitrary <<@acr tcl>> command statements can be
-# used. Forwarders come with a filtering protocol which allows to
-# manipulate the argument vector processed by the forwarder.
