Debugging aid: Output variable name/value and file/line info to stderr.
Also flushes stderr to ensure buffering and a subsequent crash don't cause the message to get lost.
auto x = 5; auto str = "Hello"; // Output example: // src/myproj/myfile.d(42): x: 5 // src/myproj/myfile.d(43): str: Hello trace!x; trace!str;
