     5  // Package inspect defines an Analyzer that provides an AST inspector
     6  // (golang.org/x/tools/go/ast/inspector.Inspector) for the syntax trees
     7  // of a package. It is only a building block for other analyzers.
     8  //
     9  // Example of use in another analysis:

    15  //	)
    16  //
    17  //	var Analyzer = &analysis.Analyzer{
    18  //		...
    19  //		Requires:       []*analysis.Analyzer{inspect.Analyzer},
    20  //	}
    21  //
    22  //	func run(pass *analysis.Pass) (interface{}, error) {
    23  //		inspect := pass.ResultOf[inspect.Analyzer].(*inspector.Inspector)
    24  //		inspect.Preorder(nil, func(n ast.Node) {
