why are warnings disabled by default in rake?

I was surprised to learn that warnings are apparently disabled by default in rake:

  def broken_code
    path = '/tmp/foo'

    # create empty file
    File.open(path, 'w')

    # when warnings are enabled you get a warning here- File#new does not take a block
    File.new(path) do |f|
      puts "never get here..."
    end
  end

  task :no_warnings do |t|
    broken_code
  end

  task :warnings do |t|
    $VERBOSE = 1
    broken_code
  end

Why are they disabled? Is there a simple way to enable them, beyond setting VERBOSE=1 early in your code?

It works for me:

# Rakefile
task :foo do |t|
  File.new {}
end

Result:

$ rake foo
(in /tmp)
/tmp/Rakefile:2: warning: File::new() does not take block; use File::open() instead
rake aborted!
