The repl supports partial input, but it bases it on the error message string to determine partial input: if(src_or_err:find("no bytes$")) This could be made more explicit somehow.

Printing of regular tables is still Lua's stupid opaque method: table: 0x10c8700 so we should add some pretty-printing at some point.

Wow awesome work on the executable. Clean code, polished, all in an afternoon.
