| Foo.C: In function 'int main()':
| Foo.C:11: error: expected primary-expression before 'my_foo'
| Foo.C:11: error: expected `;' before 'my_foo'
| 
| on line 8 and 10, "Foo" is understod asa class name, on line 11 as a namespace
| Without line 11, no error message at all

Line 4 is invalid; the front-end should have issued a diagnostic there.
