pandoc-plot VS ghc

That's great news. I've been waiting for years for a dedicated 'Figure' element. The workaround was pretty brittle. It'll make pandoc-plot [0] easier to maintain as well.

That's the perfect learning project because there's something tangible at the end.

Whenever the question of "How do I learn Haskell" comes up, I always suggest to come up with a project that would be useful on its own, regardless of the technology used to create it, and use Haskell to do it. In my case it was a pandoc filter to embed plots in documents (https://github.com/LaurentRDC/pandoc-plot), which was ultimately useful to create my PhD dissertation.

There's only so much you can learn about Haskell by working through toy examples.

of course it does! what else would you call something like chicken scheme [https://call-cc.org/], ats [https://ats-lang.sourceforge.net/], or ghc [https://www.haskell.org/ghc/]? they are not "scripts", they are full-blown compilers that happen to use C as their compilation target, and then leverage C compilers to generate code for a variety of architecures. it's a very sensible way to do things.

Agree about Haskell... as far as I'm aware there is actually no declarative/easily-readable definition of the Haskell syntax that is also complete, especially when it comes to the indentation rules, and the syntax is basically defined by the very (ironically) imperatively-defined GHC parser[0].

I prefer a syntax like in Pure[1], where the ambiguous, hard to parse indentation-based syntax is replaced by explicit semicolons (Yeah, you can use braces/semicolons in Haskell as well, but most code doesn't).

GHC, the main Haskell compiler

GHC is hosted on Gitlab, the Github repo is just a mirror. So money.

Depending on who you ask, a programming language can be different things. If you ask the Haskell community, many will tell you that the language is the Haskell specification, and that what currently is being used is not Haskell itself, but an extension of Haskell that is supported by the GHC compiler. Similar to the C language, a programming language would be a specification.
