What valid JSON would be invalid MAML?

For example, Unicode escaping seems incompatible. JSON’s “\u1234” format isn’t in the spec. There is a different syntax: “\u{123456}”

You are right. And the initial question is also meaningless as there is no difference between these two:

  {"project": "MAML"}

  {project: "MAML"}
