(`rx`) Lax co-[R]epresenting object (`yo`) [Y]oneda functor mapping c[O]variantly (`xk`) Source lax [K]leisli morphism (`xl`) Target lax K[L]eisli morphism
`ryokl` : target ( source r a ) ( target ( source ( a ) ( tt o )) ( tt ( t a ) ) )

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

Type declaration with labels arrangement:

`ryokl` : target ( source r a ) ( target ( source ( a ) ( tt `L` tt `T` ll `L` t `T` l `T` o )) ( tt ( t o ) ) )

Available stretched versions (starting precedence is 5):

`ryokl_`, `ryokl__`
