Thanks for the reply, I just want to save the Map to a file and recover it. I would like to provide an API to destroy Reader and Writer to...

But that seems like a lot of work, so why not try building a `map` object and getting the Reader and Sender from it, so we only need to implement...

Yes, I want to get readhandle and mapreadref from writehandle. And generate only writehandle when new! However, in order to prevent writehandle from being abused, it should be packaged as...
