Unnecessary code block

Reports code blocks that are redundant to the semantics of the program and can be replaced with their contents.

The code blocks that are the bodies of if, do, while, or for statements will not be reported by this inspection.

Example:

  void foo() {
    { // unnecessary
      int result = call();
      analyze(result);
    } // unnecessary
  }
