/Я language (β)/Operators/yo'ya/

(`yo`) [Y]oneda functor mapping c[O]variantly (`ya`) [Y]oneda functor mapping contr[A]variantly
`yo'ya` : 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:

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

Available stretched versions (starting precedence is 8):

`yo_'ya`, `yo__'ya`, `yo___'ya`, `yo____'ya`, `yo_____'ya`, `yo______'ya`, `yo_______'ya`
