That actually depends on context! The mixin statement needs statements, but the mixin expression takes expressions. Same mixin keyword, but if it is in the context of a statement it is a statement and in the context of an expression, it is an expression.

void main() {
        int payload;
        mixin("++payload;"); // statement, ; required
int b = mixin("++payload"); // expression, ; would be wrong there and cause an error!
