Subject: using lambda, binding happens immediately?

 I have this code:


require 'test/unit'
require 'leapyear'
class LeapYearTest < Test::Unit::TestCase
   def setup
     @ly = LeapYear.new
   end
   def LeapYearTest.generate_tests
     filename = "testdata.dat"
     file = File.new(filename, "r")
     file.each_line do |line|
      year, is_leap = line.split;
      code = lambda { assert_equal(is_leap.downcase=="true", @ly.isleap?(
year.to_i)) }
      define_method("test_isleap_" + year, code)
     end
     file.close
   end
end


What I want to know is why when I use define_method("name") {block;} instead
of define_method("name", lambda{block}) the binding seems to happen later
(after the each_line loop)?

Is there a reason behind that?

Thanks,
Sammy Larbi
