The difficulty of reading this line may be emphasized by the fact that no
one seemed to notice that it has a dyadic interpretation which gives
different answers. I suspect from the discussion that this dyadic use is
unintended.
Before I noticed this, based on my initial interpretation, I would have
written this
(3 : '+/ ,".&> ({.@:":) &.> p: i. y')"0 ] 2 3 10 15
5 10 25 43
which I rind easier to read than the original.
([: +/ [: > [: ".&.> [: [ [: {.&.> [: [ [: ":&.>@p: i.) &> 2 3 10 15
5 10 25 43
The dyadic use seems mostly to return "3", so is probably unintended:
1 ([: +/ [: > [: ".&.> [: [ [: {.&.> [: [ [: ":&.>@p: i.) &> 2 3 10 15
3 3 3 3
3 ([: +/ [: > [: ".&.> [: [ [: {.&.> [: [ [: ":&.>@p: i.) &> 2 3 10 15
3 2 3 3
