Real-World Event Sourcing - incomplete/extra function clause (page 9)

@autodidaddict

The second to last function clause in esintro/es_calc_v3.exs does not have a function body and is covered by the last function clause.

def handle_event(
  %{value: _val},
  %{}
)

Good catch. This looks like it was a copy/paste fail.
