 Implementation design perfs:
 
 * Flat data structures with abstraction patterns only when necessary.
+  * Minimize distinct code-paths
+  * Use classes as "filters", keep things "mega-structed"
+  * Never pre-emtively make interfaces or interface-like patterns
 * Keep everything data-wise in the runtime unless there is a measurable performance cost.
 * Some exploratory optimizations for educational purposes.
 * Plugins are installed in the engine repo unless not possible.
 * Code almost exclusively in C++ for everything but cosmetics (this is a engineering portfolio).
 * Keep static module functions within C++ namesapces and have the in BP function libraries to expose to BPs.
+* Perfer stage-metaprogramming to C++ compiler provided templating (when possible).
