I second this idea, it would be a useful addition.
Several times, I would have used such a feature if it was available.
Instead, my preferred method is to use something similar to the
reverse_map() example.
That syntax should be added to Lua if (and only if) it was easy to implement.
Unfortunately, I doubt that the implementation is so easy: it looks
like the parser would have to look ahead an arbitrary number of tokens
before knowing what to do with the first field.
