[luatex] Linking to C libraries / TL2017 / FFI

[Patrick Gundlach]

Hello all,

I have a (probably very dumb) question regarding the new TeXlive 2017. I'd like to link C-libraries (actually written in Go, but I would start with simple cases first) to LuaTeX, without recompiling. I believe this is possible with the new LuaTeX. Is this correct? Is this supported on Mac, Linux and Windows? Is this related to ffi? 

If this is possible: is there a small howto somewhere?

Patrick (who is quite excited if this is possible)
