> Your logic would presumably interpret this as even naturals.. but ya

My logic comes from a Math background. Take any Abstract Algebra class and this notation is common.

For example: https://math.stackexchange.com/questions/1378174/how-to-deno....

To say the least I take numerous issues with the notation used, but I accept it. Since the integers and the naturals have the same cardinality, we have that Int = Nat.
