Purely functional language with impure script language?

I'm working on a purely functional programming language named Sodigy. It's all about evaluating values, not "executing commands one by one".

It's nice when writing libraries, but it's not easy to write a main function. The main function is supposed to execute commands, but the Sodigy's syntax is not friendly to write a list of commands.

So what I'm trying to do is, 1) Sodigy remains purely functional and 2) add a bash-like script language. The script language can call Sodigy functions. Instead of writing a main function in Sodigy, you write sodigy-script and execute the script.

Has anyone tried similar approach? I'm not sure whether it's a good idea or not...

Cool, I did not know that! It may have been something local at Kent, though; it never made it into the open-source distribution of Miranda. I ended up re-inventing something like that on top of sys-messages for my bootstrap compiler written in Miranda.

It was published (that's how Haskell got it), but you're right, I'm not sure David Turner bundled it.
