Can template instantiation be a POD?
Consider the following class template template<class T> struct foo { T bar; }; Is foo<int> a POD according to the standard? In general, if an instantiation of a class template creates something that would have been a POD if it were declared as a regular class, is this a POD? -- Eugene ... 10 Jan 2008 17:25

Exception class with shift operator
Hello, I would like to use a shift operator for storing information associated to an exception, as follows: #include <stdexcept> #include <string> void foo() { double x = 0.0; unsigned long u = 1; std::string s("Runtime error detected in "); // What I would like to do: throw std::runtime_er... 10 Jan 2008 17:25

Requiring client code to provide implementation file.
I'm wondering if it is possible to do the following, perhaps with some pre-processor trickery? When providing a class, we usually provide a header file with the class declaration (and possibly some inline implementations), and an implementation file. My question is: is it possible for a given framework to... 10 Jan 2008 09:51

Anonymity & Object Lifetime
Hi. I'm wondering why simply naming an object changes its lifetime. Foo foo(1); // vs. Foo(1); I image the technical reason is that the latter is an expression instead of a declaration. Is this correct? I would still like to learn what the rationale is for this difference. Why shouldn't anonymous ob... 5 Jan 2008 12:50

mixed-sign arithmetic and auto
I have had a mini- or probably micro- or even milli-epiphany: using "auto" will exacerbate C's broken unsigned arithmetic, which C++ also inherited. As we all know, in C, any expression that has unsigned within a radius of a mile will also have type unsigned. This is a simple rule but one of remarkable bluntness... 22 Jan 2008 06:05

(unsigned) char == (platform) byte ?
Hi I know that sizeof(char) == 1 (as per ISO C and C++), (if I remember well from the C++ standard text) that the definition of a byte was the smallest object that the machine could address, that a machine byte does hold a char but we don't know yet that all possible values of a machine byte can be stored in a c... 10 Jan 2008 10:24

Binding template parameters (template aliasing) in C++03
Hi I am working these days with TypeLists similar to what mr. Alexandrescu describes in his well known book. So I made a generic TransformList metafunction that applies a given single parameter metafunction on a list like: template<typename List, template<typename> class MetaFunction> struct TransformList; ... 4 Jan 2008 13:30
