Right Shoe (⊃
) is a monadic function is nested APLs which reduces the level of nesting of an array. However, its treatment of non-scalars varies between dialects. Some dialects have it extract the argument's initial element in ravel order, while others have it combine the array's elements (requiring conforming shapes or padding with [fill element]]s). Depending on which approach is taken, it is common to use the unambiguous names First and [Mix]] for these two functions.
For a discussion of all uses of the glyph ⊃
