c++/57: [parser] templates in default arguments

[Wolfgang Bangerth]

Nathan,
the following code has, if I recall correctly, invalid syntax:
---------------------------------------------
template <class T, class U>
struct A {
     static const int n = 0;
};

template <class T>
struct B
{
     template <class U>
     void foo (int = A<T, U>::n) { }
};
---------------------------------------------
In the default argument parsing, there's a "," not nested inside 
parentheses. This stops default argument parsing. If you agree, then this 
report should be closed.

Regards
  Wolfgang
