As J-P has said, you could use 'Write and 'Read (or better, 'Output and
'Input) to write to a stream.

The beginnings of an alternative, which I last worked on a while ago, is
at [1]; it's an Ada implementation of part of MessagePack[2] (boolean,
integer, float, string). Still a way to go!

Writing arbitrary data to a stream using 'Write/'Output suffers from the
disadvantage that the reading side won't know what to expect unless you
have some protocol in place. This Message_Pack doesn't eliminate this at
all.

For a while, I supported a scheme where all the data to be transmitted
had to be instances of a tagged type e.g. Base; as far as I can
remember, you output the data using Base'Class'Output and read it in
using Base'Class'Input.
