I watched Dr. Damian Conway's speech on OSCON 2008 movie clip.
And I saw unfamiliar syntax.
I know quoted words...
my @list = qw;
and I know @ARGV or filehandle with diamond operator...
my @lines = <$fh>;
my $one_line = <>;
But this expression is very suprising...
my @list =
h @ARGV, @logs;
while( <> ) {
print "$filename:\n$_" if( /with errors/ );
}
Of course, my problem is that I'm not filling in $filename in that
print statement with a value. I'd really like to be able to put the
name of the file the diamond ('<>') operator is c

Yes, but it does it before the loop starts!

This reads all the lines from all the files listed in @ARGV and does
