amulet VS kaleidoscope

One possibility would be to do something like the now-defunct Amulet language (an ML that compiled to Lua) did. You'd get accurate compiler errors, but also an additional error number that corresponds to a more beginner-friendly explanation of common reasons for the error, pulled from here, that could be accessed with amc explain 1234 on the command line or :explain 1234 in a REPL. So for example, if you tried the same kind of error as OP tried, like 1.1 + 1, you'd get this:

Kind of a side note, but I wasn't a big fan of moonscript. I don't really like the Python-like approach to syntax and it just didn't suit me. F# or Haskell handles it better, and OCaml manages to look similar without actually needing whitespace sensitivity; I think they all do it way better than Python or Python-inspired languages. I really liked the idea of of the ML-style Amulet because of this, but it's a dead project now apparently. :(

Comparing the haskell and cpp implementations of the LLVM tutorial lead me to believe it might be faster to learn haskell and implement the compiler in haskell than to implement it in cpp.

I think for writing compilers Haskell deserves to make the list. It is really excellent at creating DSLs. https://www.stephendiehl.com/llvm/

I'm no expert, but you might be interested in: https://llvm.org/docs/tutorial/

There's also a Haskell version if you'd prefer: https://www.stephendiehl.com/llvm/

Idk how to do this in python as I'm not really good with it, but in C, to make your compiler a JIT, you would `mmap` a region as writeable, write the machine code to it that you already know how to generate, `mprotect` it as PROT_EXEC instead of PROC_WRITE, cast the pointer to the region to a function pointer, and then call it. These functions may be available in the python sys package but I don't really know.

I've implemented a "JIT" that takes machine code as hex and does this. Warning: it's complete garbage with no error checking but is a good proof of concept. https://gist.github.com/martinjacobd/3ee56f3c7b7ce621034ec3e...

This is amazing. I tried following Stephen Diehl's JIT compiler in LLVM tutorial[0] a few years ago but it was already outdated (the llvm-hs library changed quite a bit), and subsequent web searches didn't turn up much.

For those interested in tutorials like this, I'd also recommend a very literate Haskell compiler for the PCF language to C[1], which is essentially lambda calculus with some primitives.

I'm currently working with llvm-hs-pure and am struggling to properly emit code for a module. I basically followed https://www.stephendiehl.com/llvm/#chapter-3-code-generation and have types like:
