Description
This is probably a less common use case. I've got a mongoengine.Document that represents a common data structure in my application, which I store in my database, and it's great for that. But it's also a generally useful class, and in one place, we create it in an inner loop (to make use of its methods) without ever touching the database.
In this case, object instantiation can take up a non-trivial amount of time, especially compared to normal Python objects:
>>> timeit.timeit('Foo()', 'class Foo(object): pass', number=100000)
0.013084888458251953
>>> timeit.timeit('Bar()', 'import mongoengine\nclass Bar(mongoengine.Document): pass', number=100000)
2.403195858001709
Is there any way to make this more efficient? Or perhaps even to signal to mongoengine: "This is never going to be written to disk, so I don't really need all the metaclass stuff"?
