/Я language (β)/Operators/yo'yo/

(`yo`) [Y]oneda functor mapping c[O]variantly (`yo`) [Y]oneda functor mapping c[O]variantly
`yo'yo` : target ( t ( tt a ) ) ( target ( source a o ) ( t ( tt o ) ) )

Original mapping of derived functor definition:

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

This operator is available for functors with multiple parameters:

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

Available stretched versions (starting precedence is 8):
