Hi,
v0.7 has a different behavior than v0.5 when using a Cocoa-Obj (NSCalendarDate)
as a key in a hash.
I must admit that I do not know what is exactly specified in Ruby, but
obviously the generated value of an hashkey of different objects is same in all
other cases if the objects itself are identical:

$ macruby_select 0.7 h.rb
{#<NSCalendarDate:0x2000df2a0>=>:x, #<NSCalendarDate:0x2000c7fa0>=>:y} #
<==== is this ok????????
{["t", "e", "s", "t"]=>:y}
{#<Date: 2010-02-01 (4910457/2,0,2299161)>=>:y}
$ macruby_select 0.5 h.rb
{#<NSCalendarDate:0x2000a3280>=>:y}
{["t", "e", "s", "t"]=>:y}
{#<Date: 2010-02-01 (4910457/2,0,2299161)>=>:y}
$ ruby h.rb
{["t", "e", "s", "t"]=>:y}
{#<Date: 4910457/2,0,2299161>=>:y}
$ ruby1.9 h.rb
{["t", "e", "s", "t"]=>:y}
{#<Date: 2010-02-01 (4910457/2,0,2299161)>=>:y}
$ cat h.rb
require 'Date'
def h(d1,d2)
h = { d1 => :x}
h[d2] = :y
p h
end
d1 = NSCalendarDate.dateWithYear( 2010, month:5, day:2, hour:0, minute:0,
second:0, timeZone:nil)
d2 = NSCalendarDate.dateWithYear( 2010, month:5, day:2, hour:0, minute:0,
second:0, timeZone:nil)
h(d1,d2)
h( ["t", "e", "s", "t"],"test".chars.to_a)
h( Date.parse("2010-02-01"), Date.parse("2010-02-01“))
