This gives the one expected line of output, but then hangs and does not exit.
$ echo '3 1 4 1 5 9 2 6 5 3 5' | zq -z 'array:=collect(this) | over array => (sort | uniq | array:=collect(this))' - {array:[1,2,3,4,5,6,9]} [...never exits...]
Repro is with Zed commit 2357e17. I bumped into it while responding to a community Slack thread.
If I rebuild the pipeline gradually, I can see where it starts to hang.
This exits ok:
$ zq -version Version: v1.17.0-74-g2357e178 $ echo '3 1 4 1 5 9 2 6 5 3 5' | zq -z 'array:=collect(this) | over array => (sort)' - 1 1 2 3 3 4 5 5 5 6 9
But introducing uniq causes the hang.
uniq

tl;dr
This gives the one expected line of output, but then hangs and does not exit.
