<pre>clang compiles well following code (since clang 3.5), but should NOT according
to standard (<a href="http://pastebin.com/aVVbjw7A">http://pastebin.com/aVVbjw7A</a>). Also see this thread
<a href="http://stackoverflow.com/questions/29661253/overloaded-lambdas-in-c-and-differences-between-clang-and-gcc">http://stackoverflow.com/questions/29661253/overloaded-lambdas-in-c-and-differences-between-clang-and-gcc</a>
#include <utility>
template <class... Ts>
class TMultiLambda: public Ts... {
public:
template <class... Fs>
TMultiLambda(Fs&&... Vs) noexcept: Ts(std::forward<Fs>(Vs))... {
}
};
template <class... Ts>
auto MakeMultiLambda(Ts&&... Vs) noexcept ->
TMultiLambda<std::remove_reference_t<Ts>...> {
return { std::forward<Ts>(Vs)... };
}
int main() {
int x;
auto a = [x](int, int) { };
auto b = [x] (char) { };
auto c = MakeMultiLambda(a, b);
c(2, 2);
c('q');
return 0;
}
P.S.
It seems you differently handle/treat methods and operator(). If operator()
change to function f() clang stops compiling this code.</pre>
