MoreLabels(3)

💖 MoreLabels(3) — the OCaml library's extra-labeled bestie 💖

okay so real talk: this is the MoreLabels page from the OCaml library, and it's lowkey one of the most useful little meta-modules out there. buckle up, bestie 🎀

✨ NAME ✨

MoreLabels — Extra labeled libraries. that's it, that's the whole vibe 💅

---

🦋 Module 🦋

the module is, literally, Module MoreLabels. iconic, no notes 👑

---

🌸 Documentation 🌸

so here's the tea ☕ — the module signature is exactly this, and it's giving "I contain multitudes":

Module MoreLabels
 : sig end

Extra labeled libraries. fr fr, that's what it says.

This meta-module provides labelized versions of the MoreLabels.Hashtbl , MoreLabels.Map and MoreLabels.Set modules. — a meta-module!! she's a package deal, she bundles up three whole modules and slaps labels on them 🌈

and here's the intended way to use her, and this is important so pay attention 🙈:

This module is intended to be used through open MoreLabels which replaces MoreLabels.Hashtbl , MoreLabels.Map , and MoreLabels.Set with their labeled counterparts.

so you open her once and she just swaps the plain ones out for the labeled ones. effortless. main character energy. ✨

For example:

open MoreLabels

Hashtbl.iter ~f:(fun ~key ~data -> g key data) table

look at those ~key and ~data labels just ✨ existing ✨ — that's the whole point, bestie. Hashtbl.iter taking ~f with a function that itself takes ~key and ~data. chef's kiss 🫶

and then she's got her three little submodules:

• module Hashtbl : sig end — the labeled hashtable, she's gorgeous 💖
• module Map : sig end — the labeled map, obsessed 🗺️
• module Set : sig end — the labeled set, a whole queen 👑

all three are just sig end in this page's rendering, so if you want the actual contents you gotta go read their own pages, iykyk 🧚

🎀 that's a wrap 🎀

no exit statuses, no environment variables, no flags to memorise — she's just a meta-module doing meta-module things 💜 this page came to you from OCamldoc (version stitched into the footer, dated 2026-06-22), so yeah, that's the source and the date, mwah, bye bestie 😭💕
