Subject: The question about 'Range' as Condition

Hi All,

I don't know why these two codes of behavior will not be the same, 
in my opinion, they are the same logic.

Thanks a lot!


Codes:
-------------------------------------------------
arr = [ 'head', 'start', 'body', 'end', 'tail' ]

# test 1
puts 'loop test:'
for i in 0...arr.size
  puts arr[i] if arr[i] =~ /start/ .. arr[i] =~ /end/
end

puts

# test 2
puts 'hard test:'
puts arr[0] if arr[0] =~ /start/ .. arr[0] =~ /end/
puts arr[1] if arr[1] =~ /start/ .. arr[1] =~ /end/
puts arr[2] if arr[2] =~ /start/ .. arr[2] =~ /end/
puts arr[3] if arr[3] =~ /start/ .. arr[3] =~ /end/
puts arr[4] if arr[4] =~ /start/ .. arr[4] =~ /end/
-------------------------------------------------



The output:
----------
loop test:
start
body
end

hard test:
start
----------
