Another thing to consider is that Perl is being demerited for TIMTOWTDI, but
Ruby is not. Yet how many ways are there to loop from 0 to 2 in Ruby?

results = Array.new

3.times           { |i| results << i }

(0..2).each       { |i| results << i }

0.upto(2)         { |i| results << i }

0.step(2)         { |i| results << i }

(0..2).to_a.each  { |i| results << i }

for i in 0..2     do results << i end

i = 0
while i <= 2
  results << i
  i+=1
end

i = 0
until i > 2
  results << i
  i+=1
end

i = 0
loop do
  results << i
  break if 2 < i+=1
end

puts RUBY_VERSION
results.join.scan /.../ do |result|
  puts result
end



There are also a few additional ways in Enumerable that aren't shown here
b/c they don't work on 1.8.6

And I left out array based solutions, because while they will work in this
small range, that is not what they are there for, and so will quickly become
unmanageable. ie [0,1,2].each {} might work but is not scalable if you want
to iterate the first hundred numbers, and is not dynamic if you want to be
able to determine your range from variables.

And I don't know enough about Perl to answer this, but I'd be interested to
know from anyone who does, whether Perl is actually difficult to read, or
whether that is just a consequence of certain styles of coding that get the
most attention or have become idiomatic within the Perl community.
