You realise that LLMs are already better at deciphering this than humans?
Trying to remember the article that tested small inlined weirdness to get surprising output. That was the inspiration for the up up down down left right left right B A approach.
So far LLMs still mix command and data channels.
And it still isn't a problem for LLMs. There is sufficient history for it to learn on, and in any case low resource language learning shows them better than humans at learning language patterns.
If it follows an approximate grammar then an LLM will learn from it.
But sure.
