Package reflect
import "reflect"
The reflect package implements run-time reflection, allowing a program to manipulate objects with arbitrary types. The typical use is to take a value with static type interface{} and extract its dynamic type information by calling Typeof, which returns an object with interface type Type. That contains a pointer to a struct of type *StructType, *IntType, etc. representing the details of the underlying type. A type switch or type assertion can reveal which.
A call to NewValue creates a Value representing the run-time data; it contains a *StructValue, *IntValue, etc. MakeZero takes a Type and returns a Value representing a zero value for that type.
