Vendor resets the main module's vendor directory to include all packages
needed to build and test all the main module's packages.
It does not include test code for vendored packages.

The -v flag causes vendor to print the names of vendored
modules and packages to standard error.

The -e flag causes vendor to attempt to proceed despite errors
encountered while loading packages.

// returns the name qualified with the package path.
func Id(pkg *Package, name string) string {
	if isExported(name) {
		return name
	}
	// unexported names need the package path for differentiation
	// (if there's no package, make sure we don't start with '.'
	// as that may change the order of methods between a setup
	// inside a package and outside a package - which breaks some
	// tests)
	path := "_"

```

Das würde bedeuten:

* Beginnend im selben Package, in dem sich dieses Modul (die Datei `app/routers/items.py`) befindet (das Verzeichnis `app/routers/`) ...
* gehe zum übergeordneten Package (das Verzeichnis `app/`) ...
* gehe dann zum übergeordneten Package dieses Packages (es gibt kein übergeordnetes Package, `app` ist die oberste Ebene 😱) ...

	because it also disables the conservative stack scanning used
	for asynchronously preempted goroutines.

The [net] and [net/http] packages also refer to debugging variables in GODEBUG.
See the documentation for those packages for details.

The GOMAXPROCS variable limits the number of operating system threads that
can execute user-level Go code simultaneously. There is no limit to the number of threads
