> A Datum now has a field for each possible type it may contain, rather than having separate interface implementations for each type. There is an additional enum field that serves as a type marker, so that when we do need to, we can inspect a type of a Datum without doing any expensive type assertions. This type uses extra memory due to having a field for each type, even though only one of them will be used at a time.

Go’s lack of an expressive type system continues to disappoint :(
