Being in libraries or in the language isn't so much the thing, because really the language is just calling into a hidden library. It's more being directly written, versus being composed of Legos that are themselves composed of Legos... that ends up drawing in a hundred thousand lines of ultra generalist code and then pre-specializing it.
