-Literal strings allow I<unquoting> by escaping the quoting construct, to indicate it I<escapes> literallization:
+Literal strings permit interpolation of embedded quoting constructs by using the escape sequences such as these:
 
     my $animal="quaggas";
     say 'These animals look like \qq[$animal]'; # OUTPUT: «These animals look like quaggas␤»
     say 'These animals are \qqw[$animal or zebras]'; # OUTPUT: «These animals are quaggas or zebras␤»
 
-C<\qq> is equivalent to double-quoting interpolation, and C<\qqw> to word quoting with interpolation. Using C<\> on any other quoting construct, and it within literal quotes will effectively allow de-literallization or the use of dynamic content within literal strings.
+In this example, C<\qq> will do double-quoting interpolation, and C<\qqw> word quoting with interpolation. Escaping any other quoting construct as above will act in the same way, allowing interpolation in literal strings.
