     This is a very basic implementation of type storage with memory and model objects interoperability.
     Currently, supports only stack register readings, but API-wise is finished.
 
+    Each untyped ref entity (reg reading, etc.) must define its own way to generate a key.
+    For reg readings it is suggested to use its 'idx' field since
+    they are sustained among all models and symbolic memory.

     TODO: support other possibly untyped refs.
