[Y]oneda contr[A]variant functor (`ya`) [Y]oneda c[O]variant functor (`yo`) `ya'yo` : t ( tt a ) `AR____` target ( source ( o ) ( a ) ) ( t ( tt o ) )

Original mapping of derived functor definition:

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

This operator is available for functors with multiple parameters:

`yia'yo` : t _ ( tt a ) `AR__` target ( source o a ) ( t _ ( tt o ) ) `yai'yo` : t ( tt a ) _ `AR__` target ( source o a ) ( t ( tt o ) _ ) `ya'yio` : t ( tt _ a ) `AR__` target ( source o a ) ( t ( tt _ o ) ) `ya'yoi` : t ( tt a _ ) `AR__` target ( source o a ) ( t ( tt o _ ) ) `yia'yio` : t _ ( tt _ a ) `AR__` target ( source o a ) ( t _ ( tt _ o ) ) `yai'yoi` : t ( tt a _ ) _ `AR__` target ( source o a ) ( t ( tt o _ ) _ ) `yai'yio` : t ( tt _ a ) _ `AR__` target ( source o a ) ( t ( tt _ o ) _ ) `yia'yoi` : t _ ( tt a _ ) `AR__` target ( source o a ) ( t _ ( tt o _ ) )
