Rename Null into Undefined
bliss.common.utils
provides a Null
object which is used to deal with uninitialized attributes or vars. Instead of using None, which could be a valid initialized value.
bliss.data.nodes.lima
also uses a Unset
concept.
I propose to rename it into something a little more explicit.
Use on of this names instead of Null
Uninitialized
Unset
Let me know, I can take care of the change.
