Re: Unused variables

[Peter Bortas @ Pike developers forum]

void remove(string file, int(0..1) dry_run)
{
        werror("Now removing %O\n", file);
        // if(!dry_run)
                rm(file);
}

Might be somewhat contrived, but leaving unused arguments like this
primarily screws up readability when scanning code. When you develop
it it's perfectly fine, but if you have moved it to production and
start turning on #strict_whatever it time to lean more towards ADA
than Perl.
