: You could just return $count; which will do the right thing.
We are testing for an empty condition. When
the count is 0 the function should return a 'true'
value meaning "true the directory is empty". If
we returned $count empty directories would return
false and directories with content would return
true. Though it appears I could have written:
return ! $count;
Or the 'golf'ish:
return ! grep ! /^\.{1,2}$/, readdir $dh;
