First, You haven't duplicated Abigail-II's expression correctly; if you do so, it will work correctly:

  if ($line =~ /^(?:(?!throw).)*$/s) {
    debug ("Doesn't contain throw");
  }

An alternative formulation, which I find slightly cleaner, is to recast it as a single negative lookahead:

  if ($line =~ /^(?!.*?throw)/) { ... }
