Ok, I understand. My mistake consist in that I tried on first and
second pass build entity model, and generate AST on third pass (plus, I have
incorrectly analysed 2-nd pass, that suggest me on infinite stages parsing).
AST generation on first pass + 2 additional passes seems match better.
Thanks to all. Subject is closed.
