I disagree completely. When people want to use something, they look at how to use it, and use it. If they use it wrong because they didn't read the directions, they *might* file a bug report, and if they do, you just post a RTFM response and move on. Most likely they post a message to d.learn and learn (or look it up on stack overflow or whatnot).

If someone does:

```d
// note no import of std.experimental.logger
main() {
   libraryFunction();
}
```

And gets log messages they didn't ask for, I think that would generate far more bug reports. Maybe not for logger, but for the poor library that decided to use it, as it likely has its name printing out with the log messages. And closing those bug reports with "you have to configure the logger away from the default" would not be met with blanket acceptance.

The end result here is: no library is going to use it (including mine).

I have to disagree as well.
The term RTFM exists because people don't read the manual.
