You could think: what does "comb(2)" do? Perhaps look at the documentation?
And then maybe realize that Simon forgot that the comb(2) should be a method on
$hex? Otherwise, how would it know what to parse?
I know it is hard to think when you're in a hurry. But you should really learn
to be able to read code, instead of copying examples only and not understanding
*how* they work.
