<div>
<pre>struct Foo {
template<typename...T> Foo(T...x) {}
};
Foo bar{1, 2, 3, {}, 5};
This gives the nonsense diagnostic:
foo.cpp:4:26: Candidate constructor not viable: requires 3 arguments, but 5
were provided
instead of a more accurate diagnostic that the nested initializer list cannot
be used due to a lack of type context.</pre>
