Description
Array#- does not remove an element of type hash (line 8):
irb(main):001:0> a = {}
=> {}
irb(main):002:0> b = {}
=> {}
irb(main):003:0> c = []
=> []
irb(main):004:0> a == b
=> true
irb(main):005:0> c << a
=> [{}]
irb(main):006:0> c.index(a)
=> 0
irb(main):007:0> c.index(b)
=> 0
irb(main):008:0> c - [b]
=> [{}]
irb(main):009:0> c - [a]
=> []
Array#uniq does not remove an element of type hash (line 7):
irb(main):001:0> a = {}
=> {}
irb(main):002:0> b = {}
=> {}
irb(main):003:0> c = []
=> []
irb(main):004:0> a == b

irb(main):007:0> c.uniq
=> [{}, {}]

Looks like both of these issues were fixed a while ago in ruby_1_8 and in ruby_1_9. You might wanna close this ticket but Kirk Haines should be informed so he can backport it to 1.8.6 (in case it's not there yet).

Issues are still present in ruby 1.8.6 (2009-08-26 patchlevel 387) [i686-darwin10.0.0]
