lens VS hoogle

They are in fact well structured and not random at all. Take a look at this:

https://github.com/ekmett/lens/wiki/Operators

A composition of functional operations over Kmett style lenses. Here's the original Haskell implementation, here's usage in JS via Ramda

The documentation of lenses is geared towards people know what lenses are. Of course this single fragment of documentation doesn't make sense if you don't know what lenses are. If you want to understand what lenses are the package links to a helpful wiki and tutorial: https://github.com/ekmett/lens/wiki/Overview

All within reach within seconds of discovering the function.

Dimensions behave somewhat like a "type system" for math. These dimensional-analysis tricks act like the trick you see in Haskell sometimes, where you can easily guess an implementation of an expression once you know it's type (or e.g. search by type signature https://hoogle.haskell.org/ )

Haskell Spotlight makes vscode a client for hoogle. It isn't too different than jumping into your browser and type https://hoogle.haskell.org/. The main advantage is that you have everything in one place

https://hackage.haskell.org/package/base and https://hoogle.haskell.org are automatically up to date and better searchable than almost any other reference of any other programming language. maintaining a redundant reference that needs to be kept up to date manually is simply stupid.

Ideally like this: https://zio.dev/reference/#concurrency

Or this: https://hoogle.haskell.org/?hoogle=fork

And yeah I get it, it's hard to Google for punctuation operators in languages because it doesn't give useful search results (but not impossible, for example, Haskell has a search engine for documentation that handles symbols/punctuation).

{ "customLocalFormatters.formatters": [ { "command": "make format", "languages": ["haskell"] } ], "emeraldwalk.runonsave": { "commands": [ { "match": "*.hs", "isAsync": true, "cmd": "make retag retag_file=${file}" } ] }, "ghcid.command": "make ghcid", "goto-documentation.customDocs": { "hs": "https://hoogle.haskell.org/?hoogle=${query}" } }

You had a look at Hoogle?

For some type signatures there is (are) only one (or only a few) meaningful implementation(s).
