I'm extending https://github.com/tweag/monad-bayes, which had it already, not sure where from. To be fair, it only had it in "dev" mode. Here's the flags in the cabal file:

So this summer I'll be working as part of a Tweag fellowship (https://www.tweag.io/blog/2020-02-14-os-fellowship/) on extending the Bayesian inference and probabilistic programming library monad-bayes (https://github.com/tweag/monad-bayes). It's a super nice library, and my goal is to make it much more user friendly (see these draft docs for example: https://monad-bayes.netlify.app/).

These questions are pretty basic, but I'm having a hard time making sure I'm doing things right. I have a .cabal file which I want to change in order to enable e.g. threading and optimization (https://github.com/tweag/monad-bayes/blob/master/monad-bayes.cabal). Looking at it, I don't see -O2 or -threading anywhere, so am I right in thinking those things aren't happening, or am I looking in the wrong place?

Thanks so much! Streamly seems like a good idea. I'll almost certainly follow up with more detailed questions after trying some things, but just for context for now, here's the code I'm trying to modify: https://github.com/tweag/monad-bayes/blob/master/src/Control/Monad/Bayes/Population.hs .

Oh OK. Then yes get a good textbook for yourself. Learn you a Haskell for Great Good (I'd suggest: https://learnyouahaskell.github.io/ over the one in the sidebar) is free on the web. But buy a book and get it soon.

So we have LYAH, also there is O'Reilly book, which is a bit old but still mostly good, many people start with this book. After any of those three you can probably decide for yourself what to use to continue the study

You can find an exhaustive list on haskell.org/documentation, but I'd recommend Learn You A Haskell (LYAH), haskell.mooc.fi, or CIS 194.

There is a community edition of LYAH that's still being updated.

In case there are any beginners stumbling upon this I just want to repeat what I said on the Discord: This code example (at least the original code OP posted - it seems to have been edited since) originates from the terrible TutorialsPoint Haskell tutorial. It is outdated and comically wrong, please don't use it. If you're looking for free Haskell tutorials I'd suggest the Wikibook or Learn You a Haskell.

I'm just under halfway through LYAH and I have to say, it's not clicking at all. I can't put my finger on it but I feel like I'm not learning much.

Might try https://learnyouahaskell.github.io/ instead.
