I like this. I also like yaml, I’ve had very few issues with it and it’s nicer to work with than json.

Json’s lack of support for trailing commas and comments makes it very annoying for everyday use.

Significant white-space is bullshit and i will die on this hill.
Yeah I just want JSON with optionally quoted keys, and comments.
Commas (at least the trailing ones), comments, and nothing else. JSON with type inference seems like an incredibly bad idea…
Significant whitespace is DRY

Languages with explicit scoping encourage you to repeat yourself.

Because yaml is not a programming language, and debugging why your whatever you’re configuring isn’t working correctly can be a nightmare. It doesn’t tell you you missed an indent on a block, it just assumes it should be there and changes the meaning.

Braces are visually clear.

I think YAML has its fair share of design flaws, but I don’t think significant indentation is one of them. It may not be a programming language (which may be debatable), but there are plenty that use syntactic whitespace.
PlatformScript: make your YAML come to life

PlatformScript is a friendly, full featured programming language with pure YAML syntax.

It’s not debatable… You linked to a programming language that uses yaml syntax, that didn’t make yaml itself a programming language… It’s not.

And I know there are plenty that use syntactic whitespace, and I hate that about all of them. Literally my only real frustration with python is due to the time of my life wasted debugging perfectly fine logic that fails because a few lines had incorrect indentation.

Because I am not counting white space when I read. Or should we just write machine code straight away?
Not sure I’m following the jump from significant white space to machine code. How are those related?
Human and machine read differently. If you ignore that (in case wity indentation), then why bother with writing human-friendly form of code, when what is going to be really executed is something else?
If anything, that sounds like an argument in favor of significant indentation, not against it. Humans and machines read differently, yes, which is why we tend to add whitespace and indentation to code even for programming languages where it’s not significant. We do that expressly because it makes the code more human-friendly, so it’s quite the opposite of ignoring their differences.
No, it is an argument against it. We indent code so that it is more comfortable to read it, not in order to make it easier to understand

You’re mistaken:

Indentation is a secondary notation that is often intended to lower cognitive load for a programmer to understand the structure of the code.

Indentation style - Wikipedia

Lol. Go on, show me how it is easier to understand structure of the code when I am 3 levels down, first two are already out of sight
That’s not a coherent argument, but you don’t have to agree with me. I think this discussion has run its course.
What a nice way to say “I can’t back my standpoint up”. Anyway, do have a good day
You are not alone, my friend
