  I thought I had a piece of dust on my screen, but as I scrolled the dust scrolled: what do these 0xB7 characters do in the identifiers? Are they just "name mangling" to keep them from being exported or something?

  I noticed another 0xB7 character in a comment, and sure enough it seems to be part of the identifiers: https://github.com/ebitengine/purego/search?q=runtime%C2%B7c...

  Very cool! I will definitely give this a try, I've been looking to build Go bindings to Mach[0] soon.

  How does this work around the stack size problem? IIRC the reason CGO overhead exists is at least partly because goroutines only have an ~8k stack to start with, and the C code doesn't know how to expand it-so CGO calls "must" first have the goroutine switched to an OS thread which has an ~8MB stack.

  One reason I think Go <-> Zig could be a fantastic pairing is that Zig plans to add a builtin which tells you the maximum stack size of a given function[1], so you could grow the goroutine stack to that size and then call Zig (or, since Zig an compile C code, you could also call C with a tiny shim to report the stack required?) and then eliminate the goroutine -> OS thread switching overhead.

  The Full-Stack Web Framework for Go

  

  Awesome!

  This would be such a game-changer for server-side rendering Javascript in Go with V8.

  I'd love to integrate this into Bud[1].

  SWIG is a software development tool that connects programs written in C and C++ with a variety of high-level programming languages.

  

  How is this any different than a mature tool such as SWIG (https://www.swig.org/)?

  I've used SWIG extensively with Python to call C code and import C headers for testing/tooling purposes.

  Oh then sure, I don't see why you couldn't use it with something like https://github.com/mediremi/rust-plus-golang
