Go: reflect: ChanOf makes "han" types instead of "chan" types

[strickyak]

1. What version of Go are you using (go version)?
   go1.7.linux-amd64
2. What operating system and processor architecture are you using (go env)?
   GOARCH="amd64"
   GOHOSTARCH="amd64"
   GOHOSTOS="linux"
3. What did you do?
   https://play.golang.org/p/7XOdJWnLVM
4. What did you expect to see? go1.6.1 says this: [ notice second line says "chan" ]
   < string >
   < chan string >
   < chan int >
5. What did you see instead? go7.1 says this: [ notice second line says "han" ]
   < string >
   < han string >
   < chan int >

If you change my test so that it says
ch := make(chan string, 3)
instead of
ch := make(chan int, 3)
it fixes the error; apparently reflect.ChanOf() only makes a flawed Type object
if a correct one is not already compiled into the program.
