The Intro on eval result not being a data is something that I don't get. If it's not data then what is it?
For an example - while technically a set of all prime numbers is data - you can't just view it in the REPL as a whole. So I interpret the "not data" notion as a shortcut to saying - a subset of data and optionally some way to navigate throgh the rest of it.
