This is a bug report for perl from eda@waniasset.com,
generated with the help of perlbug 1.39 running under perl 5.14.3.
-----------------------------------------------------------------
[Please describe your issue here]
% perl -F: -nE 'say $F[0]'
Here the user has forgotten the -a flag to split the string into @F.
The -F option specifying the split delimiter has no effect if -a
is not also given. Perl should warn (or, preferably, fail with
an error) if command line usage gives -F but not -a.
[Please do not change anything below this line]
