A modern programming language that makes developers happier.

kotlinlang

The note on this page says it was put into the `arrow-meta` repo, does anyone know whether this went anywhere?
Would love to have proper pattern matching in Kotlin -- even Java has it now! :sweat_smile:

Hi <@UTTNCEE3F> I think it refers to <https://github.com/arrow-kt/arrow-meta/tree/pattern-matching> . That has been stale for quite a while now but <@UBSK9D611> may know more.

Hi Raul and Gavin! Yes that original branch went stale. There were many changes going on within the Kotlin compiler internals at the time and I had been working more in Scala around that time as well.

But now I am working now in Kotlin daily so have been thinking about looking into this again.

Seems there may be some interest in this so I think I might resurrect this again as I find myself wanting proper pattern matching in Kotlin almost daily now :slightly_smiling_face:

Maybe the new K2 compiler and analysis API's + Arrow analysis API's might be helpful for this as well?

K2 and FIR can be used but be aware is not planned to be stable until after Kotlin 1.9 or so AFAIK.
