%module test
%{
// c code defines a static constant
static const int i=3;
%}

// declare the constant so that it shows up in the python module
static const int i;

%pythoncode %{
# try to use the constant in some python code
lookup={'i':i,}
%}

[dave]$ python -c "import test"
Traceback (most recent call last):
