Jai also leans very heavily into this I believe.

Can we get Jai compilers yet? Or is it still for in-house use only?

  What's Jai?

    It's a language written by Jonathan Blow, meant to replace C++ for game development. reportedly his game "The Witness" was written in it. He has a series of video's where he explores what the language will look like as he's developing it, and has claimed he'll open source it once he feels it's ready. He wants to maintain control until he feels it's no longer half-baked. IIRC, he demonstrates things like a music player running during compile time. It's a core tenet of his language.

      playing the jeopardy tune during long compilations would be awesomely hilarious (:

      > He has a series of video's where he explores what the language will look like as he's developing it Probably the best place to see it in it's current form is his development streams on Twitch: https://www.twitch.tv/j_blow https://www.twitch.tv/j_blow. Right now the most active streamer besides Jon is Raphael, who does a lot of work on the Jai compiler: https://www.twitch.tv/raphael_luba https://www.twitch.tv/raphael_luba. Sadly, the other people I know who stream their work with it haven't been streaming much lately.

        I must have gotten my wires crossed.

  It is in private beta. You can send an email to request access. I'm not sure of the frequency or percentage of requests that are accepted, but I have seen some people get added over time.

Jai allows compile time execution of system calls. We (the D team) considered this, and rejected it because we didn't want users to be worried that there'd be some malicious source code that could delete their file system if they just ran it through the compiler.

  Not GP. I agree with this, but there may still be times when it is needed. I'm working on a system where users can run a build in an interpreter that kills the build if it tries to do anything they don't allow. An important and trusted project that needs a special permission will probably be allowed to do that, but random packages? Not at all.

    The trouble is, malicious people can be very clever at evading such protections. We didn't want to get into an arms race with them. I'm old enough to remember ActiveX.

      They can, but this is a trillion dollar problem (cloud) now so it's harder than you might imagine
      - ghoward 4y ago
        I think you meant to reply to me, not Walter Bright. And yes, this is a trillion dollar problem. I may be just some bloke with an idea, trying to make it happen. However, I have the free time to try, so why not?

        I meant to reply to Walter, he isn't a server guy so be probably isn't familiar with how modern systems defend against this problem.
