Subject: Closures syntax ?

Hi, im new to ruby. I ve qaquestions about closures

1) if i defiene this


def loopN n, &b
  i=0
  while (i<n) do
     b.call
     i+=1
   end
end

Why the first and the second calls dosnt works and the third works?
1.1) loopN 5, {puts "hola"}   # compile error , parse error unexpected
"{", expected "$"
1.2) loopN 5 {puts "hola"}    # compile error , unexpected tString.
1.2) loopN (5) {puts "hola"}  # works

thanks
