-reflect api that avoids runtime reflect.Value cost
-
-* reflect get/set interface{}, with type checking
-* reflect get/set unsafe.Pointer, without type checking
-* `reflect2.TypeByName` works like `Class.forName` found in java
-
-[json-iterator](https://github.com/json-iterator/go) use this package to save runtime dispatching cost.
-This package is designed for low level libraries to optimize reflection performance.
-General application should still use reflect standard library.
-
-# reflect2.TypeByName
-
-```go
-// given package is github.com/your/awesome-package
-type MyStruct struct {
-	// ...
-}
-
-// will return the type
-reflect2.TypeByName("awesome-package.MyStruct")
-// however, if the type has not been used
-// it will be eliminated by compiler, so we can not get it in runtime
-```
-
-# reflect2 get/set interface{}
-
-```go
-valType := reflect2.TypeOf(1)
-i := 1
-j := 10
-valType.Set(&i, &j)
-// i will be 10
-```
-
-to get set `type`, always use its pointer `*type`
-
-# reflect2 get/set unsafe.Pointer
-
-```go
-valType := reflect2.TypeOf(1)
-i := 1
-j := 10
-valType.UnsafeSet(unsafe.Pointer(&i), unsafe.Pointer(&j))
-// i will be 10
-```
-
-to get set `type`, always use its pointer `*type`
-
-# benchmark
-
-Benchmark is not necessary for this package. It does nothing actually.
-As it is just a thin wrapper to make go runtime public. 
-Both `reflect2` and `reflect` call same function 
-provided by `runtime` package exposed by go language.
-
-# unsafe safety
-
-Instead of casting `[]byte` to `sliceHeader` in your application using unsafe.
-We can use reflect2 instead. This way, if `sliceHeader` changes in the future,
-only reflect2 need to be upgraded.
-
-reflect2 tries its best to keep the implementation same as reflect (by testing).
