ghci-ng VS hoogle

I've only dabbled with GHCI. I've used it as a standalone REPL for trying out small things, the same way I'd use a Python or Javascript REPL. I haven't used the REPL /the/ developer interface to the program. In Clojure, I would (1) start a REPL server, (2) connect to it from my editor, and (3) send expressions to it. I didn't develop Haskell that way, though I think it was possible with Intero[1].

Within the Clojure community, there's a perception that the Clojure REPL is one of its strongest selling points[2].

Are you using the REPL actively when developing?

This can be a very useful tool. In the Haskell community there's https://hoogle.haskell.org/ which serves a similar purpose. For me this search engine is indispensable anytime I try to do anything in Haskell.

https://hoogle.haskell.org/ can help you find the function that you're looking for.

As for "words"... yes, possibly not the best name. But also so common that everyone that has ever written any Haskell code knows it. Such as Java's System.out.println

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.
