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.
