Len looks like it should be O(1), but the need to check for non-zero-length repeated fields makes it at minimum O(n) where n is the number of repeated fields. In practice, it's O(n) where n is the number of fields altogether. The Len function is not especially useful, easily duplicated with Range and a counter, and can be surprisingly inefficient. Drop it.

Next Generation Go Protocol Buffers
WARNING: This repository is in active development. There are no guarantees about API stability. Breaking changes will occur until a stable release is made and announced.
This repository is for the development of the next major Go implementation of protocol buffers. This library makes breaking API changes relative to the existing Go protobuf library. Of particular note, this API aims to make protobuf reflection a first-class feature of the API and implements the protobuf ecosystem in terms of reflection.
