error checking ℕ𝕠𝕞 syntax

This document outlines or sketches how to error check the nom syntax. It will try to use new state-of-the-art error checking techniques that I have discovered (like pushing an error* token to reduce the verbosity of the script) and it will be a “green-fields” ℕ𝕠𝕞 parser meaning that I will not base the code on previous translators or compilers. This will allow me to use things that I have learnt since about 2019 when I first managed to code a decent implementation of the ℙ𝕖𝕡 engine and the ℕ𝕠𝕞 language.

I should be able to use this error checker as the basis for an html pretty-printer

   read;

   # literal tokens, for readability maybe 'dot*' and 'comma*'
   [;,.{}] { add "*"; push; .reparse }

   # command names
   [:alpha:] {
     while [:alpha:]; put; clear;
     # check for valid command or abbreviation
   }
