`multierr` allows combining one or more Go `error`s together.
+## Features
+
+- **Idiomatic**:
+ multierr follows best practices in Go, and keeps your code idiomatic.
+ - It keeps the underlying error type hidden,
+ allowing you to deal in `error` values exclusively.
+ - It provides APIs to safely append into an error from a `defer` statement.
+- **Performant**:
+ multierr is optimized for performance:
+ - It avoids allocations where possible.
+ - It utilizes slice resizing semantics to optimize common cases
+ like appending into the same error object from a loop.
+- **Interoperable**:
+ multierr interoperates with the Go standard library's error APIs seamlessly:
+ - The `errors.Is` and `errors.As` functions *just work*.
+- **Lightweight**:
+ multierr comes with virtually no dependencies.
+

-// writer.Close(),
-// conn.Close(),

+// errors := multierr.Errors(err)
+// if len(errors) > 0 {
+// fmt.Println("The following errors occurred:", errors)
+// }
//
-// Advanced Usage
+// # Appending from a loop
+//
+// You sometimes need to append into an error from a loop.
+//
+// var err error
+// for _, item := range items {
+// err = multierr.Append(err, process(item))
+// }
+//
+// Cases like this may require knowledge of whether an individual instance
+// failed. This usually requires introduction of a new variable.
+//
+// var err error
+// for _, item := range items {
+// if perr := process(item); perr != nil {
+// log.Warn("skipping item", item)
+// err = multierr.Append(err, perr)
+// }

+//
+// multierr includes AppendInto to simplify cases like this.
+//
+// var err error
+// for _, item := range items {
+// if multierr.AppendInto(&err, process(item)) {
+// log.Warn("skipping item", item)
+// }
+// }
+//
+// This will append the error into the err variable, and return true if that
+// individual error was non-nil.
+//
+// See [AppendInto] for more information.
+//
+// # Deferred Functions
+//
+// Go makes it possible to modify the return value of a function in a defer
+// block if the function was using named returns. This makes it possible to
+// record resource cleanup failures from deferred blocks.
+//
+// func sendRequest(req Request) (err error) {

+// return err
+// }
+// defer func() {
+// err = multierr.Append(err, conn.Close())
+// }()
+// // ...
+// }
+//
+// multierr provides the Invoker type and AppendInvoke function to make cases
+// like the above simpler and obviate the need for a closure. The following is
+// roughly equivalent to the example above.

+// conn, err := openConnection()
+// if err != nil {

+// }
+// defer multierr.AppendInvoke(&err, multierr.Close(conn))
