2.91.40: missing features in namespaces

[micschne@stud.uni-frankfurt.de]

Hello World,

My C++ compiler is 

	gcc version egcs-2.91.40 19980608 
	(gcc2 ss-980502 experimental)

[1]  B. Stroustrup: "The C++ Programming Language" (3rd Ed.)
 

I did some experiments with namespaces and
most worked pretty well. There are two things,
that are not supported:

1) namespace directives and declarations should
   be allowed within a function body (s. [1] 8.2.2,
   [1] 8.2.3) :

	#include <iostream>

	namespace ns {
		int x = 5;
	}

	int f()
	{
		using namespace std;	// egcs: "parse error"
		using ns::x;		// ditto

		cout << x;		// should be ok

		return 0;
	}


2) If we call a function `f' from namespace `ns' with
   an argument `a' of type `T' declared in the same namespace, 
   no namespace resolution should be necessary ([1] 8.2.6) :

	namespace ns {
		class T { /*...*/ };
		int f(const T&);
	}

	int g(const ns::T& a)
	{
		int i = f(a);	// ok:    implicit `ns::f(const T&)'
		return f(i);	// error: no `f(int)' in scope
	}
