Esto es bastante simple (no muy útil), pero nos ayudará a centrarnos en cómo funcionan las sub-dependencias.

## Segunda dependencia, "dependable" y "dependant" { #second-dependency-dependable-and-dependant }

Luego puedes crear otra función de dependencia (un "dependable") que al mismo tiempo declare una dependencia propia (por lo que también es un "dependant"):

	if !globalBrowserEnabled {
		globalBrowserEnabled = true
		defer func() { globalBrowserEnabled = false }()
