What does Ctor::Ctor prototype mean?
Hi, For a class ABC. Can we declare the Ctor as ABC::ABC()? In particular for a class template, what is the semantics? Please look at the code below. It doesn't compile on VC2008. class Base { public: Base::Base() {} virtual ~Base() {} } ; template <class T> class ABC : public Base { public: ABC:... 29 Jul 2010 20:42

on a quest for C++ hamcrest matchers library
Hello, Can some kind person please point me in the direction of the hamcrest matcher library ported to C++? The main hamcrest web pages say that there is a port but do not provide any links. My googling has been unsuccessful. The closest I have found is some hamcrest-like matchers in GoogleMocks. But they seem t... 28 Jul 2010 19:33

why are missing return statements from non-void functions not a compilation error
> One of them, C4715, is "not all control paths return a value". Sure enough, the function in question has a return type of int, and there are various embedded returns but no final return at the end, a control path that it can get to. So my question is, "why is this not a fatal compilation error?". I... 27 Jul 2010 17:15

Boost.Any doesn't respect type conversion
For example: int f(boost::any pi) { if(int i = boost::any_cast<const int*>(pi)) { return i; } } int main() { int a = 1; f(boost::any(&a));//throw an bad_any_cast exception } Boost::any can not handle derived-to-base cast too, so It seems boost::any is not appropriate to be ... 27 Jul 2010 17:15

why are missing return statements from non-void functions not a compilation error
In the process of cleaning up some legacy C++ code I have been eliminating various compiler warnings I am getting from Visual Studio. One of them, C4715, is "not all control paths return a value".

Why cannot I get initializer_list like objects without using them? Please, why wouldn't the code (1) below work with c++0x?
