     8  // Each statement in the list of statements for each case clause must be
     9  // terminated with a semicolon. No semicolon is present for the labeled
    10  // statements and because the last token is a colon ":", no semicolon is
    11  // inserted automatically.
    12  //
    13  // Both gccgo and gofmt correctly refuse this program as is and accept it
    14  // when the semicolons are present.
    15  
    16  // This is a test case for issue 777 ( https://golang.org/issue/777 ).
