1) refuses to operate on stdin; requires a filename argument, which is so irritating.

2) doesn't accept values that jq accepts

  % time jq -r '[expression]' < parcels | wc       
      365    1454    7978
  jq -r  < parcels  1.39s user 0.00s system 99% cpu 1.390 total
  wc  0.00s user 0.00s system 0% cpu 1.390 total

  % time ~/.yarn/bin/q  '[expression]' parcels | wc
  q: internal error, uncaught exception:
     Yojson.Json_error("Line 56, bytes -1-32:\nJunk after end 
  of JSON value: '{\n  \"OBJECTID\": 155303,\n  \"BOOK\"'")

That's super weird, I think most people use jq for bash pipelines.
