// and only targeting queries as opposed to commands etc.

Seven Stages of Becoming a Go Programmer
  • stage 1: You believe you can make Go do object oriented programming. You want to do this by using clever struct embedding.
  • stage 2: You believe goroutines will solve all of your problems. You want to use goroutines for anything and everything that you can, who cares if the code becomes a bit more complicated
  • stage 3: You believe that instead of object oriented programming, interfaces will solve all of your problems. You want to define everything in terms of interfaces
  • stage 4: You believe channels will solve all of your problems. You want to do everything from synchronization, returning values, and flow control using channels.
  • stage 5: You now believe Go is not as powerful as people claim it to be. You feel like you're stripped of all of the nice tools and constructs that other languages provide.
  • stage 6: You realize that stages 1~5 were all just your imagination. You just didn't want to accept the Go way. Everything starts to make sense.
  • stage 7: You are now at peace
