I’ve had a very positive experience using Lua as an extension language. I was writing a text editor at the time. I wanted as much of the core code/actions to be written in Lua as possible, as I’ve always disliked very thin scripting APIs that sit on top of opaque native procedures. I was able to wrap a handful of native functions in Lua code, then write the remaining 85% of the editor core in Lua. Everything was very fast and the process was straightforward. I’d definitely choose it again.
