Simply trying to compile this should show you that either it is illegal code, 
or your compiler wouldn't support it anyway.  For a matter of record, I would 
believe it to be illegal (or "malformed" or some other term) code.
I took your code above as is (a.cc) and threw it at gcc 2.7.2.1:
[0] d:\src\z>gcc -c a.cc
a.cc:8: parse error before `('
This would be referring to the "int ::foo()" line - and the parse is before 
the opening parenthesis of foo().
At any rate, the code makes zero sense to me anyway - what is it exactly that 
you are trying to do?  Is it just try bizarre scenarios, or is there a 
problem that would be solved by this construct?  If the latter, let us know 
what it is and we should be able to help you with the "correct" method.  :-)
