Wow, that's a bug. I've filed DevDiv#807268 "meow(const T&) should be considered to be more specialized than meow(const Args&...)" in our internal database with a reduced repro:

C:\Temp>type meow.cpp
#include <stdio.h>

template <typename T> void meow(const T&) {
    puts("meow(const T&), GOOD");
}

template <typename... Args> void meow(const Args&...) {
    puts("meow(const Args&...), BAD");
}

int main() {
    meow(1729);
}

C:\Temp>cl /EHsc /nologo /W4 meow.cpp
meow.cpp

C:\Temp>meow
meow(const Args&...), BAD

Thanks,
STL
