Euphoric Codecs & Dazzling Rainbows
summary
ZIO Schema 2 claims a clean rework: the giant 65-term ADT becomes a 65→7 term reflect and codecs derive from a simple six-method trait, with box-free construction and deconstruction that avoid tuple boxing and primitive boxing for zero allocations in the generic path. It adds reflective optics (optics that carry schema data) to enable introspection, value-level patches and registry-backed serialization, and ships with zero dependencies and reported large performance wins.
