I have seen a lot of links introducing the variadic templates. But I have never seen any compilable example that demonstrates this approach.
Could someone provide me with some links in which such compilable examples can be found?
Variadic templates are part of the C++0x standard which is not yet officially released. They are supported by gcc since version 4.3, but you need to enable support for C++0x by adding the compiler switch -std=c++0x.
