--- Comment #1 from Petr Pisar ppisar@redhat.com --- I confirm both the issues.
-f option searches in perlfunc and perlop. perlop contains a X<< <> >> index entry for =head2 I/O Operators section:
=head2 I/O Operators X<operator, i/o> X<operator, io> X<io> X<while> X<filehandle> X<< <> >> X<< <<>> >> X<@ARGV>
There are several I/O operators you should know about. [...] If an angle-bracket-based globbing expression is used as the condition of a C<while> or C<for> loop, then it will be implicitly assigned to C<$_>. If either a globbing expression or an explicit assignment of a globbing expression to a scalar is used as a C<while>/C<for> condition, then the condition actually tests for definedness of the expression's value, not for its regular truth value.
=head2 Constant Folding
This text from "=head2 Constant Folding" line, including, should not be printed. This can be debugged with "perldoc -D -T -u -f '<>' 2>&1 |less" command.
