Would it be possible to obtain the AST (or S-Exp) from a given source file in Unicon?

There is a way (now) after some work I did late last year. It's not documented and may yet be removed. Look at the procedure Progend in .../uni/unicon/unigram.y for details.

This is a special case, isn't it? Not only it happens after the big inhale but it's hidden behind yacc. That most likely means there is no way to use this in a normal Unicon program. Or is there? It might be difficult to replicate because there is a lot of magic from x1 to classes.
