Subject: rescuing a function

Hello,

I've normally handled exceptions by "rescuing functions" in roughly this
manner:

def test_function(args)
  puts "blah blah blah"
rescue Exception=>e
  puts "blah blah blah: #{args.inspect}"
end

However, I'm using a new IDE now that's giving me a warning about the
reference to "args" in the rescue clause: "Local variable can be
uninitialized." I figured that's impossible, since it's a required argument
to the function. Should I just ignore the warning, or am I actually doing
something wrong? I suppose the alternative would be:

def test_function(args)
  begin
    puts "blah blah blah"
  rescue Exception=>e
    puts "blah blah blah: #{args.inspect}"
  end
end
