Returns  if there are no such elements. foldable-ixA variant of the  where the resulting  b is  !. Possibly can be more optimized. foldable-ix:Function to find out the 'indices' of the elements in the ² structure (from the left with indices starting from 0) that equal to the first argument. Returns empty list if there are no such elements. Uses two passes through the structure.  foldable-ix:Function to find out the 'indices' of the elements in the Ä structure (from the left with indices starting from 0) that equal to the first argument. Returns empty list if there are no such elements. Uses just one pass through the structure and additional & operation on the resulting list with .  foldable-ix4Inspired by the Data.Vector.slice function from the vector" package. Takes a 'slice' for the ± structure converting it to the list. The first argument is the 'index' of the element in the structure starting from 0 from the left. The second one is the length of the slice.        *foldable-ix-0.2.0.0-C7R8RQlW8A1KSbUtd2JahCData.Foldable.IxThreeInFourBangB34TwoInThreeBang2B23LTwoInThreeBangB23findIdx1 findIdx1'findIdxs findIdxsL1 sliceToLists2L$fEqThreeInFourBang$fEqTwoInThreeBangbaseGHC.RealIntegral Data.FoldableFoldable GHC.MaybeNothingMaybeghc-prim GHC.TypesIntGHC.Listreversefoldl'
