kotlinlang

is it the same functional argument as for not using exceptions, i.e mapping them to some monad / adt?

I asked something similar not long ago: <https://kotlinlang.slack.com/archives/C0B8Y8BHC/p1549444553099600?thread_ts=1549444553.099600&amp;cid=C0B8Y8BHC>

Honestly, I don't think there is a good justification to that except the rare case when you don't want to break the stream. Most probably on UI level.

have we all been jake-ified with that talk?

btw how do you comunicate custom errors like ..lets say input cannot be empty string -- throw custom exception?

Yes, a custom exception. Could be a sealed class with different exceptions... And the consuming side remains clean, I just pick whatever I want to handle with `when` and everything else is being logged or shown as a generic error. What talk btw, do you have a link handy? :simple_smile:

I mean, looking at it again, .it looks like ui layer, as we said where to map, right?
