Common examples of things it cannot express include reflect.Invalid, reflect.Interface, Reflect.Complex128 and more. It is not reversible because some information may be either added or lost. For example, reflect.Array and reflect.Slice are both converted to a Type of KindList, and KindFunc names the arguments of a func sequentially. The lossy inverse of this is Reflect.

If this match finds a possibility against a partial type, the status will be set to the "partial" string, and if it is compatible with the variant type it will be "variant"... Comparing to a partial can only match "impossible" (error) or possible (nil).

	Less(Value) bool // to find the smaller of the two values (for sort)
	Cmp(Value) error // error if the two values aren't the same
	Copy() Value     // returns a copy of this value
	Value() interface{}
	Bool() bool
	Str() string
	Int() int64
	Float() float64
