TWiR quote of the week

[TomP]

Advice by @alice, relevant to every Rust nauplius who attemps self-referential structs. (emphasis added)
From How to resolve "error[E0499]: cannot borrow ... as mutable more than once at a time" in this case - #3 by alice

When you have a lifetime <'a> on a struct, that lifetime denotes references to values stored outside of the struct. If you try to store a reference that points inside the struct rather than outside, you will run into a compiler error when the compiler notices you lied to it.
