I have a passing interest in esoteric languages, and one day I was talking with my partner we had an interesting idea: What if there was a programming language without return statements? You still had functions, but instead of them returning at the end or when you invoked return, you defined them alongside a condition expression. When this expression evaluates to true, the function exits.
He and I spent a while going back and forth about some possible semantics for this language. In general, we tried to follow a pattern of making the language usable, while simultaneously making it intentionally somewhat obtuse to write. We settled on removing if and while loops, as those could be easily emulated by functions.
The current implementation of the language is interpreted but typed to an unspecified degree - which personally, I feel is fitting for a language meant to be intentionally annoying to use.
