I appreciate this comment more than you can imagine.

On a related note, I don't think that

```C++
      if (verbosity == eDWIMPrintVerbosityFull) {
        StringRef flags;
        if (args.HasArgs())
          flags = args.GetArgString();
        result.AppendNoteWithFormatv("ran `frame variable {0}{1}`", flags,
                                     expr);
      }
```
is entirely accurate, either.. The DIL interpreter here is set to `lldb::eDILModeSimple` which is not how it is configured in the actual `frame variable` command. Is that something we should note?
