I'm sure I'm missing something obvious, but this has been bothering me... the Reference refers in various places to top-level variables and bindings that apparently excludes module bodies, as in section 1.2.1: "A top-level binding is a binding from a definition at the top-level; a module binding is a binding from a definition in a module…”. It gives this example in section 1.1.9: "For example, in the program ... (define y (+ (let ([x 5]) x) 6)) ... both y and x are variables. The y variable is a top-level variable, and the x is a local variable.” But I can’t figure out how such a thing can exist, because Racket always insists that any definitions I write must be inside a module, either implicitly via #lang, or explicitly. It seems like the only possible top-level form is a module form. Can someone explain this paradox to me? Thanks.
