<div>
<pre>This:
struct A {};
auto a = decltype(A{});
produces this error:
4 : error: expected '(' for function-style cast or type construction
auto a = decltype(A{});
~~~~~~~~~~~~~^
Either the user meant something like:
auto a = decltype(A{}){};
or it meant "using" instead of "auto":
using a = decltype(A{});
While the current error message is technically correct, it should be more user
friendly. It would be better if it would suggest both options in a note.</pre>
