If you're going to solve the problem of shell scripting, one particular itch that I have is that shell scripts, or at least the sufficiently complex ones, are often strongly dependent on availability of local executables, sometimes even specific implementations or versions. I had a shell script on my desktop that would automagically extract any archive I threw at it. Nice. So when I was working on android through a shell, I wanted the same convenience and so I scp'd the script onto my phone. It wouldn't run. Only worked with GNU tar, as opposed to any other tar, like bsd tar or busybox's. Having a language that provides system-independent abstractions of ls, tar, top, or the other way, that clearly indicates upon which binaries it depends, would greatly improve script usability. It'd be nice if running an oil script would automatically warn me that I need GNU tar >= version x.xx.
