<pre>This is an MSVC bug, due to their missing / incorrect implementation of
two-phase name lookup.
Within the second definition of f:
template <std::size_t x, typename ... Args>
auto f(const M<x>& , Args && ... args)
{
return f(args...);
}
... the third 'f' has not yet been declared and thus is not found by
unqualified name lookup. So once the recursion reaches this overload, it can
never "go back" to the third overload.
If the namespace is removed, the third overload can be found by
argument-dependent name lookup.</pre>
