// - It must not have been prohibited by the caller to Parse (some callers
// need a full AST).
// - The outer scope must be trivial (only global variables in scope).
// - The function mustn't be a function expression with an open parenthesis
// before; we consider that a hint that the function will be called
// immediately, and it would be a waste of time to make it lazily
