Ruby seems like a great fit for Lambda and anything non-natively supported is often just not worth it.
Ruby's benefits—simple and readable syntax, great for scripting through small problems—strike me as just right for a serverless environment. Ruby isn't exactly natively great at the kinds of things we ask it to do as a server-side language powering Rails etc.
Anyway, as a Rubyist, this is lovely to me. I'd love to hear others' takes.
