> powerful as yaml

Can you make an example of the power of yaml that makes it more like a programming language (in particular vs JSON)?

not OP but: tags (custom data types), more builtin data types (dates etc), more syntax variations (heredocuments, multiple ways to write a string,a boolean, etc), comments, references+aliases.

The language is vast, and most people use it without knowing it.

I love YAML, but I wish there was a "strict&sane yaml subset".

All those are good examples of yaml complexity but none of that is anywhere near what even a simple programming language can unleash (variables, loops, functions, recursion etc)

You can do recursion in YAML, and it ends badly: https://en.wikipedia.org/wiki/Billion_laughs_attack#Variatio...

Recursion without termination doesn't produce a useful computation
