[Watched] Go at Google

http://www.infoq.com/presentations/Go-Google

Interesting points in Go that I learned from this presentation

  • You can not have unused import statement. Makes code cleaner and faster compilation time.
  • Favor small duplication over including big dependency to use only small part of it
  • No implements declaration required for implementing an interface. Safety from static typing and flexibility from ad-hoc type.
  • Gofix - Cool tool for changing the code to fix language version incompatibility issue.
