Comment (by SimonKing):
I am still shocked that garbage collection works differently in doc tests
than in an interactive session, but anyway: Here is an example that works
both interactively in in a doc test.
{{{
sage: class SomeClass(UniqueRepresentation):
....: def __init__(self, i):
....: print "creating new instance for argument %s"%i
....: self.i = i
....: def __del__(self):
....: print "deleting instance for argument %s"%self.i
....:
sage: O = SomeClass(1)
creating new instance for argument 1
sage: O is SomeClass(1)
True
sage: O is SomeClass(2)
creating new instance for argument 2
deleting instance for argument 2
False
sage: del O
deleting instance for argument 1
sage: O = SomeClass(1)
creating new instance for argument 1
}}}
