When you give a method a block in Ruby (which is really what you're doing here), and you've defined it as a Proc, you need to pass the variable holding the Proc with an ampersand in front of it. This is because while code blocks and Procs conceptually do the same thing, they are not. The ampersand tells Ruby "hey, convert this to a code block for me".
