Is that accurate? > According to our talking about this topic, I'll explain something ;-P My goal is not to hash arbitrary object. As I said, I'm dealing with Server-design and web-framework, so what I need is to hash bytevectors and strings. Since Guile2 uses character-string instead of byte-string, I have to mention strings separately. > Thanks!
