A Sandbox for custom programming languages
I've noticed a lot of people have invented custom programming languages (ever heard of Pyth?) I've also noticed that people post challenges they think would be cool in the Sandbox. Here is my proposal: a Sandbox where you can post your custom languages and interpreters.
You write a submission like this:
interpreter's code here
People then can use the language with credit (if allowed?), comment on it, etc.
Is this a good idea?
