Using Perl for over 20 years, today I got surprised by something I don't understand. On Windows 10, using Strawberry Perl 5.22, I run the following one-line script from which I expect no output:

use Win32::Daemon;

But, surprise, this is the output:

BEGIN Win32::Daemon ...
      require Exporter;
      require DynaLoader;
      bootstrap Win32::Daemon;
      done
END Win32::Daemon ...
DONE Win32::Daemon ...

This output goes to STDOUT, not to STDERR, and I would like to get rid of it. What am I missing?
