Comprehensive optics integration between polytropos open records and variants and Edward Kmett's lens ecosystem.
Bridges the unified flat runtime representation Polytropos.Core.Rep to standard Control.Lens typeclasses:
positional lenses (Control.Lens.Tuple.Field1 through Control.Lens.Tuple.Field9), label-based lenses (Polytropos.Lens.fieldLens),
container indexing (Control.Lens.At.Ixed and Control.Lens.At.At keyed by field name), single-pass homogeneous
traversals (Control.Lens.Each.Each), and first-class profunctor prisms (Polytropos.Lens.prismVariant) for open
variant constructors with O(1) tag dispatch.
Keeps the core polytropos packages lightweight and free from transitive dependencies.
Start at the front door module Polytropos.Lens for complete documentation, usage guidelines, and worked examples.
