The first section on https://doc.rust-lang.org/stable/book/closures.html can be difficult to understand for novice programmers, particularly the line "Anonymous functions that have an associated environment are called ‘closures’, because they close over an environment." It's difficult from this context to understand what "environment" is referring to.

Yeah, this definition is kind of embarassingly self-referential 😓

This is to address issue rust-lang#28803 by improving some of the references to closures, to explain what they are more clearly, while hopefully still being concise.
