$ dmd -run tester.d
file:        tester.d
function is: tester.main
function is: void tester.main()

You can even get the calling function name:

```
import std.stdio;
void main()
{
    log("hello");
}

void log(string msg, string file = __FILE__, int line = __LINE__, string fn = __PRETTY_FUNCTION__)

{
    writeln(file,":",line,"|", fn,"|> ", msg);
}
```
