[Glass] 0.01 copy == 0.01

Hi guys,

I was checking some differences from sixx exported files from Pharo and
GemStone and I noticed in GemStone equal floats (but "different" instances)
were serialized like if they were the same instance. Then I did some

| anObject |
anObject := OrderedCollection new.
anObject add: 0.01.
anObject add: (Float readFrom: '0.01').
anObject first == anObject second
-> true


0.01 copy == 0.01
-> true

So...is this a compiler optimization? Is it something related to the fact
that SmallDouble are immediate objects?
