A second point is that you should review perllexwarn specifically the section titled What's wrong with -w and $^W as it will demonstrate scenarios where the local trick you showed above doesnt work. Localizing $^W is in no way a replacment for no/use warnings.

    I didn't see anything there which doesn't follow from first principles (assuming one is aware of the delocalized nature of the checks done by perl). Not to say it isn't, umm, valid; it's just nothing new.

      Well the fact that 
      local $^W=0;
