Afaik there's no language - the pseudocode can be written however you want. And the costing money to compile? If you're prompting an llm you're already doing that, just with prose instead of pseudocode. I'm not sure this approach is a good idea, but it might be - and imo it's worth trying :)

I have to admit, I am unsure if this article was some sort of parody.

Technically speaking everything costs money to compile in the form of electricity. This is just...inefficient compilation.
