A word on scope

The last topic we’ll cover in our service locator deep dive is scope, which comes down to how you manage what services are being registered, where the registration is happening, and how the locator is accessed – all depending on context.

For starters, everything we did with our BasicLocator and GenericLocator classes can be made into a singleton.
