During the formal review for Beast, a valid point was raised that the facilities for interacting with the chunks which make up a chunk-encoded was insufficient for some use-cases. I added more interfaces to addresses the use-cases but I never got feedback from the stakeholders about the design. It is now September 10th, and the "pencils down" deadline for making changes to Beast ahead of the 1.66.0 scheduled release is October 25th. As I have not gotten any feedback, I am asking the community if there is anyone out there who would like to review the new chunk-encoding facilities. As of yet, no one in the wild has used them. Or if they have, I did not hear of it. This is the documentation for the chunking: http://www.boost.org/doc/libs/master/libs/beast/doc/html/beast/using_http/ch...
