Consider such EO snippet:

[] > jeff
  $ > self
  [] > say-hello
    stdout self > @

Here, self was introduced on a purpose, in order to make jeff itself reusable in the say-hello. Thus, self is not redundant. However, redundant-object complains as such:

The object "self" is redundant, consider inline it instead (redundant-object (Single))

We should not complain in this case, I believe
