I don't like this article all that much but I do like the MAML format the author wrote this to promote. It seems like it’s everything that’s good about JSON, plus everything fixed for human writing, and nothing more.
Hats off, wish my package.json and build.yml were package.maml and build.maml.
MAML is an improvement from JSON, but does not improve the data types much (although it does make one improvement, which is that it distinguishes integers from floating point), although the syntax is improved.
