In a recent thread "Why is overloading operator. (member operator)
forbidden", someone wrote a code like the following:
template <typename R, typename... Argtypes>
class gen_send {
private:
string funcname;
public:
R &operator()(Arg types... arguments) {
// serialize and send
// wait for return value, return value
}
};
Is that legal? I mean, is it legal to do the following:
template<typena me T, typename... ARGS>
void foo();
Does that mean that there could be many template parameters? If so,
how could I know how many template parameters were added? By template
specialization?
Thanks in advance,
KK. 5 3379

No, it was just an incomplete example.

Not in the current standard C++, but variadic template arguments are
most certainly included in the next C++ revision (it's already in the C
++09 draft)
Read the latest revision of the proposal itself: http://www.open-std.org/jtc1/sc22/wg...2006/n2080.pdf
And the latest proposed wording: http://www.open-std.org/jtc1/sc22/wg...2007/n2242.pdf
The latest full C++09 draft: http://www.open-std.org/jtc1/sc22/wg...2006/n2134.pdf

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
