/Я language (β)/Operators/ya'yo/

(`ya`) [Y]oneda functor mapping contr[A]variantly (`yo`) [Y]oneda functor mapping c[O]variantly
`ya'yo` : target ( t ( tt a ) ) ( 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` : target ( t _ ( tt a ) ) ( target ( source o a ) ( t _ ( tt o ) ) )
`yai'yo` : target ( t ( tt a ) _ ) ( target ( source o a ) ( t ( tt o ) _ ) )
`ya'yio` : target ( t ( tt _ a ) ) ( target ( source o a ) ( t ( tt _ o ) ) )
`ya'yoi` : target ( t ( tt a _ ) ) ( target ( source o a ) ( t ( tt o _ ) ) )
`yia'yio` : target ( t _ ( tt _ a ) ) ( target ( source o a ) ( t _ ( tt _ o ) ) )
`yai'yoi` : target ( t ( tt a _ ) _ ) ( target ( source o a ) ( t ( tt o _ ) _ ) )
`yai'yio` : target ( t ( tt _ a ) _ ) ( target ( source o a ) ( t ( tt _ o ) _ ) )
`yia'yoi` : target ( t _ ( tt a _ ) ) ( target ( source o a ) ( t _ ( tt o _ ) ) )

Available stretched versions (starting precedence is 8):

`ya_'yo`, `ya__'yo`, `ya___'yo`, `ya____'yo`, `ya_____'yo`, `ya______'yo`, `ya_______'yo`
