Hi, I have a question related to monads transform...

# arrow

[jtonic]

Hi,

I have a question related to monads transformers.
Is the following still valid in version 0.7.0?

OptionT.monad<EitherKindPartial<String>>().binding {
val a: Int = OptionT(anakinAge).bind()
val p: Int = OptionT(padmeAge).bind()
(a - p).absoluteValue
}.value().ev()

The example is from the book ‘’' Functional Kotlin ‘’'.
First OptionalT was not found in dependencies so I added the arrow-data.
Is there another arrow dependency I need to configure in gradle?
Thank you for your support.
