Also, a related question about the <syntaxhighlight lang=apl inline>1/⊢</syntaxhighlight> part: why make a scalar probe into a vector before searching in the Unique/Nub? I see that doing the search without increasing the probe to rank 1, as in <syntaxhighlight lang=apl inline>(∪⍳⊢)'A'</syntaxhighlight>, does not give an error… | Also, a related question about the <syntaxhighlight lang=apl inline>1/⊢</syntaxhighlight> part: why make a scalar probe into a vector before searching in the Unique/Nub?

:Nub-sieve used to be computed like that, but it was a mistake. (∪⍳⊢)'A' would give a scalar, which then errors in ⍳⍨ [[Adám Brudzewsky]] 14:54, 29 June 2023 (UTC) | :Nub-sieve used to be computed like that, but it was a mistake.

:"Bad meme" is what Roger Hui called it. The term probably made it into some of his publications (Tolerant Unique?), and could be cited if so; otherwise it should be removed.
