Bug ID: 42072
Summary: [[nodiscard]] should work on constructors
Product: clang
Version: unspecified
Hardware: All
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: C++
Assignee: unassignedclangb...@nondot.org
Reporter: jordan_r...@apple.com
CC: blitzrak...@gmail.com, dgre...@apple.com,

C++20 says nothing about the behavior of [[nodiscard]] on a constructor; it
would be useful for that to result in a warning for RAII temporaries:
PrettyStackTraceString("oops"); // warning
PrettyStackTraceString stackTraceRAII("okay"); // no warning
(I suppose this behavior would also apply to [[nodiscard]] on the entire class,
which it currently doesn't.)
