Ask HN: What's the role of a standard library for a language aimed at FaaS?

I was musing to myself about niches for programming languages, and started thinking about Function as a Service platforms. I realized that a lot of the "batteries included" that goes into a language's standard library are obviated or at least heavily overlap with the FaaS platform functionality. How do you see this division of responsibilities evolving? What might make a language specifically designed for FaaS different?
