Also that whole “NaN ≠ NaN” business…

See that’s one of the parts that is actually almost in line with other languages. In Go, for example, nil ≠ nil because nil is, by definition, undefined. You can’t say whether one thing that you know nothing about is at all like something else that you know nothing about. It really should raise an exception at the attempt to compare NaN though.
