This is not an exhaustive list of all interfaces in Go's standard library.
I only list those I think are important.
Interfaces defined in frequently used packages (like io, fmt) are included.
Interfaces that have significant importance are also included.
All of the following information is based on go version go1.8.3 darwin/amd64.
FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.
