This step is now finished, patch attached. You can notice some
additional stuff that has been added as well, which currently is
unused but will be used in future patches. You will notice that this
patch makes lily spit out lots of Junking Event messages, which are
harmless.
oh btw, there is one thing that strikes about the "unique" member/argument.
It's type is rather arbitrarily set to int. Isn't it more sensible to
make it an SCM value, and leave it up to the deliverer of the music
stream to assign unique SCM values?
Second question: the whole concept of unique seems a bit out of place to
me: the number is essentially a marshalling device, making it possible
to refer to a specific context inside a stream, saved as a file, but I
don't see why it should be stored inside the Context struct. I think it
would be more appropriate to generate the numbers via a
map<Context*, int>
member of the stream writer.
