it's hard to come back to work schedule, changing time to summer time also didn't help.
but slowly I'm going on track, on sunday was looking into bindings in pn editor, i need to finish it in some form, I'm getting tired of it.
meanwhile I'm reading about Warren machine and Prolog implementation, just for fun, to see how Prolog is implemented and what can be borrowed to the pn editor, because i don't feel that double recursion is a good solution.
my rework of small esp board is finally done, and I'm glad that it's working.
