I don't feel strongly either way.

Also, both the array and the sequence solution result in a solid 8-to-12
bytes of known data at the beginning so file(1) will be very happy.
(ps: It already knows about 55799)

{I've re-implemented my code with a CBOR Sequence, but I'm annoyed that I
haven't found a decode in C that takes a getc(3)-like input stream, and eats
only as many things as it needs.  I have just abandonned tinycbor for QCBOR.}
