writeln is not aware of anonymous unions inside of structs (probably classes too). The attached file crashes when run.

Code copied here to increase its visibility: import std.stdio; struct Bug7230 { union { string a; int b; } } void main() { Bug7230 bug; bug.b = 123; writeln(bug); }

Thank you for improving writeln. Maybe the string tag "union" is better than "overlap": Bug7230("hello", #{union a, b, c}, 10)
