Another comment from Sorra (via email):

case dothing() of
   V1 ->
      V2 = 1; %% will be prompted to "unused variable as warning"
   _ ->
      V2 = 2;
end,
V2   %%V2 is used

So how to deal with this issue?

case dothing() of
V1 ->
V2 = 1; %% will be prompted to "unused variable as warning"
_ ->
V2 = 2;
end,
V2 %%V2 is used
