> I'm not sure making all comparable objects in Go usable as map keys is a good idea either. Was a good idea since, it's part of the spec-definition of Go: > A map is an unordered group of elements of one type, called the element type, indexed by a set of unique keys of another type, called the key type. [...] The comparison operators == and != must be fully defined for operands of the key type TFA is merely reusing that.
