  --- BEGIN ISSUE ---
  GofmtBear: Add advanced asciinema
  The coala bear GofmtBear does not have a proper asciinema.
  
  `gofmt` is a command line tool that automatically solves formatting / styling issues to the absolute coding style that Go has.
  
  I'm planning to use a working code as the sample where it's filled with mixed indentation (spaces and tabs), semicolons and demonstrate how gofmt formats the code automatically and correctly to the absolute Go coding style.
