template <class a>
class A {};
template <class b>
class B {};

A<B<void()> > x;


If you leave out the space between the two >'s at the definition of x, it fails
to compile. As far as I'm aware this should work in C++0x mode. The compiler
was run with -std=c++0x.

Really this is why  think C++0x was wrong in thinking that >> can be used as ">
>" in the template context :).

Let's ask Doug...

(by the way, Doug very kindly contributed these C++0x bits on a voluntary
basis. As a matter of courtesy, I would suggest avoiding words like "at least".
Thanks.)
