       Modules included via "use" are loaded at compile-time.  Placing conditional logic around the "use"
       statement has no effect on whether the module will be loaded.  Doing so can also serve to confuse the
       reader as to the author's original intent.

       If you need to conditionally load a module you should be using "require" instead.

       This policy will catch the following forms of conditional "use" statements:

           # if-elsif-else
           if ($a == 1) { use Module; }
           if ($a == 1) { } elsif ($a == 2) { use Module; }
           if ($a == 1) { } else { use Module; }

           # for/foreach
           for (1..$a) { use Module; }
           foreach (@a) { use Module; }

           # while
           while ($a == 1) { use Module; }

           # unless
           unless ($a == 1) { use Module; }

           # until
           until ($a == 1) { use Module; }

           # do-condition
           do { use Module; } if $a == 1;
           do { use Module; } while $a == 1;
           do { use Module; } unless $a == 1;
           do { use Module; } until $a == 1;

           # operator-do
           $a == 1 || do { use Module; };
           $a == 1 && do { use Module; };
           $a == 1 or do { use Module; };
           $a == 1 and do { use Module; };

           # non-string eval
           eval { use Module; };

       Including a module via "use" in bare blocks, standalone do blocks, or string evals is allowed.

           # bare block
           { use Module; }

           # do
           do { use Module; }

           # string eval
           eval "use Module";
