Dang, just like PHP (no built in set)

And yet there is a generic in array function.

...which is O(n). Unless the set is trivially small, better to coerce your data to key types and use array_key_exists().

I never said it was good, but it exists. Most of my PHP code utilizes kv arrays everywhere possible.
