The dividing line between what's a language and what's the IDE is fairly arbitrary. E.g. a language could conceivably come with a tool chain that includes CLI-driven refactoring, and an "IDE" would only need to be a graphical interface calling it.

How do you figure? The language defines the runtime semantics in a way no IDE or refactoring tool does. It's a very bright line, unless you're conflating the distribution package of the language with the language itself.
