That's not what I asked.
You stated that
 return? <expr>
was equivalent to
 return <expr> or None
If that was the case then the two code snippets _I_ posted should be
equivalent:
 return? something() return something() or None
 return? somethingelse() return somethingelse() or None
 log("didn't find an answer") log("didn't find an answer")
 raise ValueError raise ValueError
If the two snipped above are not equivalent, then
 return? <expr>
is isn't equivalent to
 return <expr> or None
