There are a couple of pitfalls:
- It's possible to introduce a hard to debug error `infinite recursion` when shadowing a name, the simplest example being `let b = 1; a = rec { b = b; }; in a`.
- Combining with overriding logic such as the [`overrideAttrs`](https://nixos.org/manual/nixpkgs/stable/#sec-pkg-overrideAttrs) function in {term}`Nixpkgs` has a surprising behaviour of not overriding every reference.
A common pitfall is to introduce a hard to debug error `infinite recursion` when shadowing a name.
The simplest example for this is: `let a = 1; in rec { a = a; }`.
:::{tip}
Avoid `rec`. Use `let ... in`.
