 We should strengthen the above $A_\infty$ axiom to apply to families of collar maps.

 We will not pursue this in detail here.
 
+A variant on the above axiom would be to drop the ``up to homotopy" and require a strictly associative action.

 Note that if we take homology of chain complexes, we turn an $A_\infty$ $n$-category
 into a plain $n$-category (enriched over graded groups).
 In a different direction, if we enrich over topological spaces instead of chain complexes,
