Apologies, cause I'm trying to wrap my brain around this code and I have
some questions about it.
1- It seems that until 'block.call' what is getting passed into the method
parameters is being held in que (so to speak).  Or is that a wrong
interpreation.
2- How does the method know that it calls '25000 doublings' first and then
moves on to 'count to a million'.  I realize part of it is how the code is
layed out but why couldn't it just try the 25000 doublings again ?

Hope these type of questions are okay here.

TIA
Stuart

def profile block_description, &block
  start_time = Time.now
  block.call
  duration = Time.now - start_time
  puts block_description+' :  ' +duration.to_s+' seconds'
end

profile '25000 doublings' do
  number = 1
    25000.times do
    number = number + number
  end

  puts number.to_s.length.to_s+' digits'
  # That's the number of digits in this HUGE number.
end

profile 'count to a million' do
  number = 0
  1000000.times do
    number = number + 1
  end
end
