## Más motivación

Mira esta función que ya tiene type hints:

package cmd

import (
	"syscall"
)

// RenameSys is low level call in case of Linux this uses syscall.Rename() directly.
func RenameSys(src, dst string) (err error) {
	return syscall.Rename(src, dst)

## Editor support

In your editor, inside your function you will get type hints and completion everywhere (this wouldn't happen if you received a `dict` instead of a Pydantic model):
