I rarely encounter any code using `define()` for anything more than
extremely minimal environment details these days, and even then, it usually
leads to loading an immutable `Environment` object that is then passed
through dependency injection (container or not) to runtime services.
What are the possible use-cases for this, besides enumeration types?
