       | That is a great looking tutorial. Can't wait to try it. Thanks!

       | question is also whether LLMs can correctly understand long flows
       | of concatenated operations. Any ideas?

         | very quickly because there's a combination of reading
         | "backwards" (push order) and forwards (execution order) needed
         | to maintain context. At any time a real Forth program may
         | inject a word into the stack flow that completely alters the
         | meaning of following words, so reading and debugging Forth are
         | nearly the same thing - you have to walk through the execution
         | step by step unless you've intentionally made patterns that
         | will decouple context - and when you do, you've also entered
         | into developing syntax and the LLM won't have training data on
         | that.
         | 
         | I suggest using Rosetta Code as a learning resource for Forth
         | idioms.
