Right. The Guile printer has no option of that sort yet. Quickly I
would think that this should work:
--8<---------------cut here---------------start------------->8---
(use-modules (oop goops))
(define-method (display (bv <bytevector>) port)
(format port "#vu8(~{#x~x~})" (bytevector->u8-list bv)))
--8<---------------cut here---------------end--------------->8---
but I haven't tested it.
