Yes, very nicely put.
Right now I would not even consider doing that in Lua. I would cycle
back and forth with the C interface code getting it right - loading and
reloading a shared library (or static, in the embedded case). Then on
the target I'm stuck with whatever the interface code produced.
If I could just return the value as a number then even if the Lua layer
had some problems I could still manipulate the number from the interpreter.
But it's not a show-stopping problem, just an inconvenience.
