 /**
  * Test codec for Moshi (https://github.com/square/moshi)
- *<p>
- * Challenges here are mostly due to rather exotic API that Moshi exposes: it seems
- * to aim at highly optimized I/O handling, buffering; but the end result is something
- * that is difficult use in ways other than just buffering the whole contents in
- * memory. Since the goal here is to minimize actual buffering overhead there does not
- * seem to be a good match, and what we shall do then is to build a JSON String,
- * write that in varius no-op outputs. This is not optimal, but with given API there
- * isn't much we can do, without digging knee-deep in obscure buffer/sink classes
- * that Moshi exposes from ok-io.
- *<p>
- * If anyone wants to tackle write-to-Stream / write-to-Writer cases, PRs happily accepted.
