Implement substitution of a function parameter pack for its set of
instantiated function parameters, enabling instantiation of arbitrary
pack expansions involving function parameter packs. At this point, we
can now correctly compile a simple, variadic print() example:
#include <iostream>
#include <string>
void print() {}
template<typename Head, typename ...Tail>
void print(const Head &head, const Tail &...tail) {
std::cout << head;
print(tail...);
}
int main() {
std::string hello = "Hello";
print(hello, ", world!", " ", 2011, '\n');
}
