@mm0821 Sorry for not merging right-away! Is this still up-to-date?

[mm0821]

That's my fault. I marked it as draft, since I wanted to check whether I could simplify some comments (they are quite verbose in parts) or maybe even convert this into a case study. But I never found the time. It's quite old and I have to recheck whether it still works with the current version of Effekt.

[mm0821]

This should work with the (my) current Effekt version now. I guess the check here failed because the new syntax for block parameters is not yet supported on this branch (as it is quite a bit behind :smile:).

You can merge it, if you like. I don't know when I will have time to revise it and I fear will forget about it again...

@b-studios Now that there are great case studies for probabilistic programming in Effekt, it is probably not necessary to turn this into a case study (I will likely forget about it anyway). Thus, you can just merge it, in case you want to keep it as a somewhat more elaborated example for testing, or otherwise just close the PR.

I think it is value to keep this. I rebased and updated the comment syntax.
