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
