 =head0 What's Missing
 
 Perl 5 isn't perfect, but it's malleable--in part because no single
-configuration is idea for every programmer and every purpose. Some useful
+configuration is ideal for every programmer and every purpose. Some useful
 behaviors are available as core libraries. More are available from the CPAN.
 Your effectiveness as a Perl programmer depends on you taking advantage of
 these enhancements.
