The @optics ksp codegen (using "io.arrow-kt:arrow-optics-ksp-plugin:1.0.2-alpha.42" ) seems to have a bug: if I put @optics on a data class with 3 or fewer fields it generates code with first, second, third which is great because arrow.core.Tuple3 has those fields.

But once I hit 4 fields it starts generating code with a, b, c, d which fails because arrow..core.Tuple4 does not have those fields (it has first through fourth) -- is this a known issue?

Ah looks like this is my issue: https://github.com/arrow-kt/arrow/pull/2654

For posterity: the solution was to pull in version 1.0.3-alpha.1 instead
