Ast_helper.Pat(3)

Okay bestie, welcome to the Ast_helper.Pat(3) page from the OCaml library — it's the Patterns corner of Ast_helper, and we're going through every single val together. No skipping, no cap. 💅✨

✨ NAME ✨

Ast_helper.Pat - Patterns

Like, that's the whole name section, and it ate. 🎀

🎀 Module 🎀

Module Ast_helper.Pat

That's the module address, bestie. Keep it cute and keep it exact. 🫶

💖 Documentation 💖

The docs open with the nested module situation:

Module Pat
 : sig end

Then we get the Patterns label and the full signature lineup. You'll see ?loc:Ast_helper.loc and ?attrs:Ast_helper.attrs showing up all over — I'm keeping them exactly where they belong. 👑
