      A bit more hacking, and Blodwen is now writing Scheme programs, so I don't have to. I'm looking forward to finding out how efficient this isn't.https://twitter.com/edwinbrady/status/1020027247175045121 …

      I've been programming in Scheme today and having lots of fun. Don't tell anyone...

      It turns out Chez Scheme is remarkably fast, and with appropriate optimisations, Blodwen beats Idris... Conclusion: from now I will use run time systems written by Not Me :)

      Is this available somewhere? I looked on github the other day but didn’t see anything relevant.

      Very soon. I have a small amount of tidying to do before pushing.

      Great! I’ve often wondered why more people don’t use Lisps as compilation targets.

      I resisted because I imagined it would be slow. It turns out it often is (I tried a couple), unless the lisp in question is Chez Scheme :). Especially if you turn off the dynamic checks.

          What I'd really like is a lisp that's specifically designed as a compilation target, but I suppose the target audience for such a thing is very small.

          Common Lisp implementations like sbcl are also known to be fast. I think the closest thing to what you’re talking about is the language Mark Tarver specifies as a target for Shen.
