The feature to find the value inside the nested map.

[Christophe De Troyer]

Hi,

What you are describing can be done with "lenses". They're a functional construct to get/update data from nested data structures. 

While googling I found an older discussion on this mailiing list http://erlang.org/pipermail/erlang-questions/2015-September/086068.html.

Hope that helps.
