Subject: Question: arrays v. ranges and *.each

The results of the following code just seem strange to me:

  print "\nTry 1:"
  print [1..10].class, "\n"
  [1..10].each { |x| print x, "\n" }

  print "\nTry 2:"
  print [1..10].pop.class, "\n"
  [1..10].pop.each { |x| print x, "\n" }

I would have thought that either 1) try 1 would output a sequence of
numbers, and try 2 would result in an error (no such method
Integer#each); or, 2) try 1 would output a series of numbers and try 2
would result in an error (no such method Range#pop).  Perhaps - another
option would be 3) try 1 would result in '1..10' and try 2 would result
in something like '1..1' or an error?

I'm confused...
