Sounds like `Opa!`, which was a language plus a meteor-like framework. The language itself was really nice with some interesting type-level features, but the built-in framework was the selling point. But all that ultimately got in the way for doing anything that wasn't built into it, which ended up being pretty much anything beyond toy prototypes. The language got dragged down because of it.

That said, it came out around the same time CoffeeScript did, and nobody uses CoffeeScript anymore either. So probably the fate was inevitable regardless of whether the framework was included in the language or not.
