We have a Cookiecutter template for our Django projects and I decided to replace the Makefile with invoke. Everything works very well, invoke is more flexible than the previous solution. Thanks for the great software!

Unfortunately the tasks package I created works only with Python 2. Python 3 raises a "RuntimeError: maximum recursion depth exceeded while calling a Python object". I was able to track down the cause. It's invoke.tasks.call being used to build a list of pre-targets. The task wrapped with invoke.tasks.call works stand alone. Maybe my solution to build the pre-tasks list is not correct?

Do you have a full traceback handy? I'm not using this combo of feature+interpreter myself, but AFAIK it ought to work fine (i.e. your use of mixed object references & call() objects should be a fine way to implement things), so hopefully it's just a bug (& a hole in test coverage, presumably).

I hope this helps:

Yup, that does help (obviously, once it enters final recursion, the rest doesn't, but the top part is pretty critical :D). Something to do with how we deepcopy or perform attribute access. Gives me some starting points when I take a look. Thanks!

I wrote a test that triggers the problem in this commit.

For explaination:
I added a file with content of the documentation with the modification that I create a collection manually.

In the test I use the Collection.from_module() to load the file. That call ends in a RecursionError very similar to the traceback that @keimlink posted.

Hope that helps a little bit.
PS: During investigation I had the feeling that Lexicon or one of its base classes needs a own __deepcopy__ implemention. I never did something like this, so I could be wrong.
I think Python 3.4.3 or 3.5.0 make no big difference. ;)

Add missing __deepcopy__ to Call class
Having __getattr__ without __deepcopy__ causes infinite

is also updated to cause the error fixed in this commit.

Fixes pyinvoke#257

Tested our task that triggers the problem originally and it works as expected. Thanks a lot!
