I have recently been using save_session a bit, and I uncovered what I
believe is a bug. If the worksheet of the session that I'm trying to
save contains a cython function, then load_session chokes. For
example:
var1 = 1
var2 = 2
var3 = srange(1,10000)
var4 = range(1,3000)
var5 = 1234.123456
%cython
def test(double x):
return x
save_session('test_session')
and then I save and exit, and re-enter the worksheet
load_session('test_session')
and I get
Traceback (most recent call last):

When I ran save_session with verbose = true, I noticed that it saved
test, which according to the docstring shouldn't have happened. Does
anyone have any workarounds for this issue?
