A PR to improve `struct->vector` for CS would be welcome. There relevant code is here:
https://github.com/racket/racket/blob/master/racket/src/cs/rumble/struct.ss#L1221 As you'll see, the synthesized name is currently whatever comes out of Chez Scheme's `inspect/object` interface. It could instead involve a case dispatch on fixnums, bignums, etc., to improve on the `simple` label that `inspect/object` produces. There may also be Chez Scheme versus Racket terminology to bridge, such as `byte-string` instead of `bytevector`.
