It's worse than Java and Python and JavaScript I think? The languages that were always disliked for CLI/TUI/GUI apps because of unnecessary bloat they bring due to their runtimes. It's not impossible to use this ofc, it's just inferior to alternatives with minimal runtime, so such an app might be considered a temporary solution to use before someone rewrites it in Rust or Zig or C and people have no reason to use slower and more resource hoggy version. Many people even choose to avoid Emacs for slow startup times, now imagine if something like grep was starting a virtual Lisp Machine underneath. This is why I think it's more promising to consider it for apps and niches that people never tried to keep minimal, such as games and webservices, even if it doesn't have native coroutines or whatever. Using non-standard solution is almost a non-issue and invisible to end user while startup times and RAM usage are very visible. Also, ofc there's definitely unique things that become available with something that's just as programmable in runtime as it is in development stage. So some kind of very polymorphic app that benefits from growing more native code in response to user actions, could benefit from it. I don't have many ideas of what app really needs this though. In the past, like two decades ago, I've seen a person using SBCL with some kind of unofficial continuations or green threads for backend webdev in commercial setting. I also remember someone using it in context of virtualization systems, but don't remember their exact usecase. Also quick search shows there are some modern takes on coroutines as well: https://atgreen.github.io/repl-yell/posts/sbcl-fibers/ https://atgreen.github.io/repl-yell/posts/sbcl-fibers/
