Consider the following, totally contrived, code. The compiler

tst39.d(21): Error: constructor `tst39.B.this(string s)` is not
callable using argument types `()`
tst39.d(21): constructor `tst39.B.this` hides base class
function `tst39.A.this`
tst39.d(21): add `alias this = tst39.A.this` to
`tst39.B`'s body to merge the overload sets
But I haven't yet found a way to use this guidance to resolve
the error. I _can_ add this to B:
When you add an empty constructor, the code still runs without an
error
```d
class Counter : StaticCounter {
string msg;
this(string str) { msg = str; }
this() {} // added Salih
}
class StaticCounter {
static int id;
this() { ++id; }
}
import std.stdio : writeln;
void main() {
with ( new Counter() )
id.writeln(": ", msg);
with ( new Counter("Hi, Mom!") )
id.writeln(": ", msg);
}
```
