 =head2 How can I know how many entries are in a hash?
 
 If you mean how many keys, then all you have to do is
-take the scalar sense of the keys() function:
+use the keys() function in a scalar context:
 
-    $num_keys = scalar keys %hash;
+    $num_keys = keys %hash;
 
-The keys() function also resets the iterator, which in void context is
-faster for tied hashes than would be iterating through the whole 
-hash, one key-value pair at a time.
+The keys() function also resets the iterator, which means that you may 
+see strange results if you use this between uses of other hash operators 
+such as each().
 
 =head2 How do I sort a hash (optionally by value instead of key)?
