Or in phobos, like std.stream.OutputStream.write(char[]) (and the
associated read(char[])).
It writes a size_t with the length of the following char-array.
Considering that this is even used on the network (with SocketStream)
this might lead to problems (write on amd64 and read on i386 or the
other way round).
I'd suggest to always write the length as a (u)long - or uint,
char-arrays/strings that are bigger than 4GB are just insane, anyway.
(Java uses short in a similar method, IIRC).
