• Raison d'être This unscientific benchmark:

| Command | Mean [ms] | Min [ms] | Max [ms] | Relative | |--------------------------+------------+----------+----------+---------------| | =swaylayout= | 0.5 ± 0.2 | 0.4 | 1.7 | 1.00 | | pipe =swaymsg= into =jq= | 28.8 ± 2.1 | 26.6 | 35.9 | 52.85 ± 15.14 |

e.g. 36-68x times faster than the naive solution
