a comment on my own:
even every type of the above mentioned is possible, there are 
slightly differences between them:
1. As I don't want to be able to instantiate the type itself, I 
would like to drop ubyte*.
2. If I want to be able to slice a iota, I have to initialize it 
with the last number. But the object, which stores the pointer 
does not need to know anything about this number. So, I rather 
would not like to pass this number only for being able to 
instantiate the iota struct.

So this leave me again with the void* and a pointer to a strange, 
not constructible struct...
