Up to two small comments below, this is looking good:
The implementation of copy can probably be simplified a bit by using
"super":
{{{
sage: class bla(SageObject):
....: pass
....:
sage: x = bla(); x.a = []; y = copy(x)
sage: id(x), id(y), id(x.a), id(y.a)
(204820300, 205533580, 208011212, 208011212)
sage: class bla(SageObject):
def __copy__(self):
res = copy(super(bla, self))
res.a = copy(self.a)
return res
....: ....: ....: ....: ....:
sage: x = bla(); x.a = []; y = copy(x)
sage: id(x), id(y), id(x.a), id(y.a)
(204866636, 204866156, 205535372, 204820300)
}}}
In the ElementWrapperTester: __repr__ => _repr_
