Perl now allows the arrow to be omitted in many constructs
involving subroutine calls through references. For example,
-C<$foo[10]-E<gt>('foo')> may now be written C<$foo[10]('foo')>.
+C<< $foo[10]->('foo') >> may now be written C<$foo[10]('foo')>.
This is rather similar to how the arrow may be omitted from
-C<$foo[10]-E<gt>{'foo'}>. Note however, that the arrow is still
-required for C<foo(10)-E<gt>('bar')>.
+C<< $foo[10]->{'foo'} >>. Note however, that the arrow is still
+required for C<< foo(10)->('bar') >>.

writing to read-only filehandles does).
