# Blocks
# 
# Any method can take a block, and use 'yield' to call it.
# We can figure out whether there's a block with 
# block_given? but usually you just yield, since Ruby will
# give a nice ArgumentError if no block was supplied.
def yielder(it, num)
  num.times { yield it }
end

yielder("Hi!",2) { |param| puts param }

# You can also explicitly declare a method to take a block.
# You have to use this form if you want to do anything
# beyond calling the block.
# 
# Blocks are procs for this purpose.
def blocky(&block)
  p block     # don't call - inspect
