23492	F objects are no longer deepcopy-able	ris	nobody	"I suspect the culprit is commit 3a66035107a640c4905f0a5f247a45f32dbe16d7 ""Removed F.__deepcopy__()"" because apparently ""The method didn't change standard __deepcopy__ in any way."".

Well, in 1.7.0:


{{{
>>> from django.db.models import F
>>> from copy import deepcopy
>>> f = F ( ""something__some_field"" )
>>> f.name
'something__some_field'
>>> g = deepcopy ( f )
>>> g.name
AttributeError: 'F' object has no attribute 'name'
}}}

Paste back in the same __deepcopy__ method removed in 3a66035107a640c4905f0a5f247a45f32dbe16d7, and:

{{{
>>> from django.db.models import F
>>> from copy import deepcopy
>>> f = F ( ""something__some_field"" )
>>> f.name
'something__some_field'
>>> g = deepcopy ( f )
>>> g.name
'something__some_field'
}}}

Tadaa!

Can we have it back please?
