[MAYBE?] Design Pattern Support (Command, State, ECS)

[zacharylayne]

Const type arguments can probably be leveraged in software design patterns, namely command & state patterns and ECS (entity component systems). Designs might couple very well with .NEXT TypeMap, which offers generic methods providing dictionary-like behavior while being backed by a one-dimensional array.

Is it worth the effort to create high-level abstractions for these patterns that incorporate const type argument functionality? Which patterns should be supported?
