  "%032x" % self.to_i
end

#to_path ⇒ Object

A string suitable for using as a path name –

Ex.

urn:uuid:3c0dce44-80a8-11dd-a897-001ff35a0a8b =>
urn_uuid/3c0dce44/80a8/11dd/a897/001ff35a0a8b

It’s well possible there are more perspicacious choices for points to split the string, but until we hit that limit this’ll do.
