Could you give us the full code? Because this could never work (line isn’t defined, neither is region)

Oh, yes, I know, I had the same problem: you can only pass arguments to commands that are writable in JSON.

So, it’s

  • list
  • dict (called object in JSON)
  • numbers
  • string

If it’s not one of those, it’s not gonna work. So, you can convert your region to a list: [line.begin, line.end], and, in your command, transform the list into a region: sublime.Region(args.line[0], args.line[1]).

BTW, I don’t understand how the args thing in you DoFunnyCommand could works…
