Status: newneeds_review

There is currently no implementation that this case would cover, but it is conceivable that it might occur. However, because of this, it is not something I can easily add a doctest for.

hmm, func(x) should depend on x, no ?

Ah, crap. I forgot to change that back to x. I will correct this tomorrow when I get to my office.
