I'm struggling to parse this

[dequeb]

Hi,

I extracted this grammar from Microsoft documentation. It has many points that I don't know how to process properly:

• identifiers are not case sensitive
• user-created identifier must not reuse reserved identifier
• there are rules that said a token must start on a new line
• there are rules that said a token must be a character except some others
• the priority of expression operators is express as a comment in the documentation, not in the langage definition.

Moreover, the result is quite long. Thanks in advance for taking the time to look at it.

Can you possible create a smallest possible reproducible issue, so we can answer one question at a time?
