 =head2 What's the difference between "delete" and "undef" with hashes?
 
 Hashes contain pairs of scalars: the first is the key, the
 second is the value.  The key will be coerced to a string,
 although the value can be any kind of scalar: string,
-number, or reference.  If a key $key is present in
+number, or reference.  If a key C<$key> is present in
 %hash, C<exists($hash{$key})> will return true.  The value
 for a given key can be C<undef>, in which case
 C<$hash{$key}> will be C<undef> while C<exists $hash{$key}>
 will return true.  This corresponds to (C<$key>, C<undef>)
 being in the hash.
