In Arrow Optics, is there an equivalent of 'lift' but just to get the value? I have something like

val getId: (MyClass) -> String? = MyClass.somePath.id::getOrNull

, which works, but I would prefer to call a method instead of

::getOrNull

to return a lambda directly so I don't have to explicit the variable type.

Yes, all optics should have

lift

in their APIs. https://arrow-kt.io/docs/apidocs/arrow-optics/arrow.optics/-p-lens/index.html

But

lift

generates a function to modify the source right? I want to generate a function to get the value in the source

Oh I see. I'm sorry. Then I think your best best would be to work with

::getOrNull

. I'm not sure what you mean with

to explicit the variable type

. Is it not simply returning

(MyClass) -> String?

?

No, it returns a

KFunction1<MyClass, String?>

. I just assumed I couldn't use it as a lambda but I guess I can. Thanks for the help
