I'm currently implementing a hash map as an exercise and wondered if there is a built-in function I could use to hash keys effectively? What I'm looking for is a function that hashes any variable (of any type) to an integer.

I've been looking at the `getHash` function of the `TypeInfo` class but that only seems to return the passed pointer. Any ideas?

Awesome, thanks. Can't believe I missed that.
