-# This example implements an aspect "routing" pattern.

-# propagate an already computed context to all includes.
-#
-# This aspect, when installed in a `parametric.atLeast`
-# will just forward the same context.
-# The `mutual` helper returns an static configuration which
-# is ignored by parametric aspects, thus allowing
-# non-existing aspects to be just ignored.
