The typed version is invoked as @code{(require typed/txexpr)}. The typed version is implemented ``natively'' in the sense that it is compiled separately with type annotations. It is not a @racket[require/typed] wrapper around the untyped code. This avoids the contract barrier that is otherwise automatically imposed between typed and untyped code.
