Phobos should definitely have a serialisation module, and this seems to 
me like a good candidate.  I haven't tried the code myself, but it looks 
very clean and the examples are nice.

I consider it a huge plus that it uses an existing format that already 
has APIs for a bunch of programming languages.

Two questions:

The packer can write to an arbitrary ubyte output range, but it seems 
the unpacker is limited to ubyte[] arrays.  Would it be possible to 
unpack from an arbitrary input range?

It doesn't seem to support the real type.  It this a limitation of the 
MessagePack format or just an oversight?  Even if the format doesn't 
directly support 80-bit floats, it should be possible to wrap them somehow.
