While executing the unmodified Python2.7.3 test suite, I noticed a test in
"test_copy" that was added and fails.
It copies a instance objects, with bound methods. These objects, when copied,
trigger an error in "copy_ref", indicating that the copying of compiled methods
is not supported.
The copying of method objects appears to be supported. So Nuitka needs to cover
this too. Apparently only a "__reduce__" method may be needed.
