BTW, the modern erlang code (slide#23), looks bit more "intimidating and
crowded" compared to the extremely simple look that old Erlang code has.
One of the merits of Erlang code, cited in some language comparisons was
based on the LoC comparison, somehow the modern Erlang code seems to add a
lot of volume. Although some refactoring done by TidiEr do seem to reduce
LoC as well. Anyhow, I'm certainly bookmarking and exploring all suggestions
in that presentation.
