A few variations of the vanilla Map<K, V> that might make your life easier.

Classes

AutoMap<K, V>

Populates empty keys when getting them, based on a function that receives the key in question.

CollisionMap<K, V>

You tell it how to hash keys into primitives.  Has two interesting use-cases:

• Indexing by unordered pairs—if you want [1, 2] and [2, 1] to point at the same thing
• Indexing by objects that feel primitive but aren't—eg. regexes

Please don't use JSON.stringify for your hash function 💀

AutoCollisionMap<K, V>

Same functionalities as AutoMap and CollisionMap but in one class.
