[luatex] Linking to C libraries / TL2017 / FFI

[Patrick Gundlach]

>> 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?

still curious if anybody can confirm if this works on Mac & Linux.
