Struct TYPE as a Reference Id

Q: can the Type of a Golang object used as a unique identifier.

Reason: If the type of an object can be used as a unique key then objects, like a context object, that hold objects of uniquely different types can use the type itself as the index to retrieve the object.

Conclusion:

• the nil value of a type "StructType{}" acts as an ID.
• aliased types === original type with respect to the type's "value".
• extended types are unique versus the type extended from.

Using the syntax "StructType{}" in multiple locations in a program appears to yield the same value and can be used as a unique key in a map.
