A Basic Just-In-Time Compiler (2015)

VB.net comes to mind

Lennart Augustsson implemented a JIT for BASIC as an EDSL in Haskell using LLVM.

A blog post he wrote about it: http://augustss.blogspot.com/2009/02/more-basic-not-that-any...

The JIT itself: https://hackage.haskell.org/package/BASIC

Well, it doesn't have any control flow, symbols, or system calls, so most of the work is in setting up a buffer and calling conventions. There's also no language intermediate representation or optimiser.

The W^X machinery bans self-modifying code in the traditional sense, but there may be situations where creating little specifically-optimised gadgets like this can benefit a program.

What do you mean by "actual progress"?

Without doing fancies like this, people wouldn't be talented.

It's an educational blog post.

Chris Wellons wrote elfeed and has a day job; I think he's making progress enough. There's absolutely nothing wrong with having a hobby.
