I'd love to see a little language which compiles to _readable_ bash. Could it be so hard? There's a dead project that comes up now and then called bish.
I do think it would be a really fun project. But is there really a practical use for it? Bash is portable but not that portable if you want to care about version compatibility. I understand that it's not always possible to install a different interpreted language like Perl or Python. Maybe the use case is for platforms where you can't install other language interpreters and can't cross-compile a compiled language? It seems like a very specific situation.
EDIT: I didn't know of Bish, but from its code samples we seem to have converged on similar syntax :)
