+ * The STL unordered-map is very contrived. Some of its functionality encourages younger programmers to use
+ * the exception model. Ideally, I would like this structure to never throw an error with typical use.
+ *
+ * The array access operator is, in my opinion, poorly implemented. I do not think that this operator should handle
+ * insertions and should handle access only. This is the only data structure in STL that has this behavior, no other
+ * data structure modifies contents by inherently calling operator[].
+ *
+ * Currently, I am considering implementing this as the following:
+ * Access will be handled only via operator[]. Return value will be an optional which forces user validation.
+ * Insertions will be handled only via an insert/emplace function.
+ * Deletions will be handled only via an erase function.
