New issue 2215 by asmeurer: Failures in the examples
http://code.google.com/p/sympy/issues/detail?id=2215
While looking at issue 719, I noticed that there were several failures in
the examples. You can see them all by running examples/all.py. Here are
the tracebacks from running that in the current master:
Running: intermediate.trees
Traceback (most recent call last):
File "./examples/all.py", line 130, in run_examples
mod.main()

num = [s.coeff(n) for n in range(11)]
AttributeError: 'Poly' object has no attribute 'coeff'
