I’m not convinced there’s a need for copy-on-write bytevectors, and it
would be hard to implement, and to implement
efficiently—bytevector-mutating instructions would have to check whether
they’re accessing a CoW bytevector and DTRT.
What could be convenient though is ‘bytevector-copy’ (no bang), which
would combine ‘make-bytevector’ + ‘bytevector-copy!’.
