Hmm, SWIG's default handling of arrays isn't so great, but it allows
enough customization that they can be accomodated ("table on the Lua
side, C-style array and count argument or std::vector on the C/C++
side") with some custom typemaps and code.

[There are SWIG bugs that make this a little annoying in some cases, at
least in some versions of SWIG though...]

For my attempts at doing some of this look at
https://github.com/snogglethorpe/snogray/blob/master/snograw.swg
and search for "[" or "std::vector".
