Bug ID: 29055
Summary: Improve diagnostic for assigning a type to a variable.
Product: clang
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: Frontend
Assignee: unassignedclangb...@nondot.org
Reporter: gonzalob...@gmail.com
CC: llvm-bugs@lists.llvm.org
Classification: Unclassified
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.
