echo streaming expression - two/multiple fields

How can we echo two/multiple fields out.  The current echo expression emits
"echo" field which can be then renamed with select but if i wanted to emit
another field like id along echo, is that supported or we need to enhance
echo for that...

select(echo("A"),echo as email)

Thanks,
Susheel

Thanks, Joel.  I was trying to troubleshoot the other issue with complement
function by creating some dummy tuples.  Can you please look the other
email thread I am having issue with complement function.

Starting in Solr 6.6 there is a tuple expression which returns a single
tuple:

tuple(a="hello", b="world")

You can also do things like:

tuple(a=search(...), b=search(...))
