This is a complete mess. I want to abstract reading multiline strings
behind a function, but the lookahead requirements for that are quite
stringent. What's a reasonable abstraction here?
I really wanted to avoid getting into defining or parsing new file
formats. However, using the entire power of Lua is not ideal, as
described earlier in Konrad Hinsen's bug. In addition to everything
else, it's a vector for arbitrary code execution when someone loads an
untrusted image.
I could use JSON, but it requires ugly string escaping. Seems cleaner to
just use YAML. But YAML is complex and needs its own dependencies. If
I'm going to do my own, might as well make the multi-line string format
really clear.
I can't yet write the new format.
