[Y]oneda c[O]variant functor (`yo`) source [K]leisli category (`xk`) `yok` : t a `AR____` target ( source ( a ) ( tt o ) ) ( t o )

Looks like a big circle `yi` with a bullet point `ho` inside designating covariant position of a focused parameter equipped with a small hook `xk` designating source Kleisli category.

Original mapping of derived functor definition:

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

This operator is available for functors with multiple parameters:

`yoik` : t a _ `AR____` target ( source ( a ) ( tt o ) ) ( t o _ ) `yiok` : t _ a `AR____` target ( source ( a ) ( tt o ) ) ( t _ o )

Type declaration with labels arrangement:

`yok` : t a `AR__` target ( source ( a ) ( tt `L` tt `T` ll `T` o ) ) ( t o )

Available stretched versions (starting precedence is 7):

`yok_` `yok__` `yok___` `yok____` `yok_____` `yok______`
