(`kx`) Source co-[K]leisli morphism (`yo`) [Y]oneda c[O]variant functor (`xk`) Source [K]leisli morphism (`xl`) Target K[L]eisli morphism
`kyokl` : t a `AR____` target ( source ( tt a ) ( ttt o ) ) ( ttt ( t a ) )

Looks like a big circle `yi` with a bullet point `ho` inside designating covariant position of a focused parameter equipped with a small left hook `kx` designating source co-Kleisli morphism, a small right hook `xk` designating source Kleisli morphism and a big hook `xl` designating target Kleisli morphism.

Original mapping of derived functor definition:

: source ( tt a ) ( ttt o ) `AR____` target ( t a ) ( ttt ( t a ) )

Type declaration with labels arrangement:

`kyokl` : t a `AR__` target ( source ( tt a ) ( I `L` tt `T` ll `T'I` ttt `L` ttt `T` lll `L` t `T` l `T` o ) ) ( ttt ( t o ) )
