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)
