But maybe its possible to modify this to access without square brackets in attribute style. Instead d['q']['w']['r'] = 777 => d.q.w.r = 777 ??? already seen that this is possible, but sorry, I don't remember where... Yes, You right.

In io:format there should be double quotes around X = ~p~n, i.e io:format("X = ~p~n", [X]) I think it could be related to copy/paste error in your code.
In io:format there should be double quotes around X = ~p~n, i.e
io:format(”X = ~p~n”, [X])

The second rule is especially annoying because non-local variables are the typical mechanism for doing so. Erlang makes it difficult to get values out of list comprehensions.
