I'm trying to solve the AdventOfCode puzzles, but at least half of my time I

black box for me.

obviously }} is interpreted as part of a direct definition, red in JQT, despite

Fortunately, as NUVOC mentions, } is a replacement of ( {"0 1&.|: ).
But it cost me too much time, reason to timebox my efforts for AOC.
