10. I added implicitly_convertible<const char*,OW_String>(); It

'ab'

Any ideas why this didn't work?
Not offhand. Can you post a small test case?
#include <boost/python.hpp>
using namespace boost::python;
struct test
{
test() {}
test(const char*) {}
void foo(const test&) {}
};
BOOST_PYTHON_MODULE(test)
{
class_<test>("test")
.def(init<const char*>())
.def("foo", &test::foo)
;
implicitly_convertible<const char*,test>();
}
>>> import test
>>> t = test.test("foo")
>>> t.foo("fooagain")
