A modern programming language that makes developers happier.

kotlinlang

I'd suppose so, but asking just in case... does `copy { }` make another instance of the class on each `set` or `transform` called, or does it somehow aggregate the changes and make one copy in the end?

right now it creates a new copy each time

we have plans to make it more clever using a compiler plug-in, but right now we’re scarce in time

Oh.. I thought I understood from your video that it was better than kopykat in that sense... but nice to hear there's plans for it, thanks!

it’s better because it doesn’t copy to a mutable variable and then back again, it only creates one copy

so if you have a lot of modifications, KopyKat is better (one big copy at the beginning, one at the end), whereas Optics are better for a few changes
