Thanks. I'm really leaning towards a simple and fast dump/undump pair for
the Lua core.
I'm convinced that the best route to byte order or cross-compiling is
third-party dump/undump pairs. The files ldump.c and lundump.c are
completely replaceable; they export a single, well-defined, entry point.
The format of precompiled chunks is not sacred at all; you can use any
format, as long as ldump.c and lundump.c agree about it. (For instance,
Rici Lake is considering writing a text format for precompiled chunks.)
For the Lua core, I prefer a simple and fast one. For cross-compiling,
it should be simple to change ldump.c for instance. We just have to wait
till someone writes it and makes it available.

Ah, that's an old dream. My main problem with this is that it'll have to
be a different parser from the Lua core. I don't think lparser.c is easy
to reuse. That is a shame, because having another parser opens the door to
inconsistencies. (At least, the lexer is easy to reuse, which goes helps
