Or you can do this:

config = { "version": "1.0", "comment": "JSON has comments too!" }

I hope you're joking.

Why? It's a valid solution.

Mixing metadata in with data isn't ideal.

Mixing metadata with a serialization format isn't ideal. Want metadata? Use a markup language.

Actually it is. Then you can treat them the same way.

And since it's a configuration format, you know what keys are accepted and what keys are for the metadata, and thus won't clash.

But metadata is also data.

this is what is recommended for package.json in node. Specially "//" as the key.

That's what we did for some of our KDE build infrastructure metadata, since there was no way I was using YAML if I could avoid it for something this simple.
