First, I think it would be great if this worked - like the alias to an
update table added in 8.2 - saves a lot of typing and makes queries
much more readable.

Second, only way I see is to set this on top of a view generating your
foo and bar aliases, and go from there. Compared to rewriting the
expression each time, it has the advantages of better syntax in the end
and might yield better performance as well.
