I recently wrote some code like this:

    lang:Perl
    use Log::Log4perl qw(:easy);
    Log::Log4perl->easy_init($ERROR);
    
    use My::Module;
    My::Module->run( @ARGV );

This code leads you to believe that C<Log::Log4perl> is set up when
C<My::Module> is required, but that's obviouly not the case (think
about C<BEGIN{}> if you're stuck).

Admittedly, this is rarely a problem because C<require My::Module>
doesn't use logging functions.  But if it did (and similar situations have
bitten me before), you would spend quite a while wondering what's going on.

Avoid that confusion and say what you mean, either:

   use Log::Log4perl;
   use My::Module;
   
   Log::Log4perl->init;
   My::Module->run;

or:

   use Log::Log4perl;
   BEGIN { Log::Log4perl->init }
   
   use My::Module;
   My::Module->run;

In both of these cases, your code will do what it looks like it does,
and that's always a good thing.
