// Package inspect defines an Analyzer that provides an AST inspector
// (golang.org/x/tools/go/ast/inspector.Inspector) for the syntax trees
// of a package. It is only a building block for other analyzers.
//
// Example of use in another analysis:
//
// import (
// "golang.org/x/tools/go/analysis"
// "golang.org/x/tools/go/analysis/passes/inspect"
// "golang.org/x/tools/go/ast/inspector"
// )
//
// var Analyzer = &analysis.Analyzer{
// ...
// Requires: []*analysis.Analyzer{inspect.Analyzer},
// }
//
// func run(pass *analysis.Pass) (interface{}, error) {
// inspect := pass.ResultOf[inspect.Analyzer].(*inspector.Inspector)
// inspect.Preorder(nil, func(n ast.Node) {
// ...
// })
// return nil, nil
// }
