Re: unique_ptr and operator<<

[Jonathan Wakely <jwakely dot gcc at gmail dot com>]

This is not a question about using GCC, please don't send such
questions to this list.

Please try a general C++ forum such as http://stackoverflow.com/

(The answer is that your code is not valid C++, you can't write a
unique_ptr to a stream, but I'm not going to explain how to fix it
because that's off-topic on this mailing list.)
