Yeah, that's a whole day's work.
Maybe not for you or me. But for someone who needs half a day to type
my $test = do {local $/; <HANDLE>};
it could easily be.

    half a day to type

    You keep dwelling on that, but I think you're misdirecting. He wrote, "spend half a day writing and debugging code", not "half a day to type in one line".

    If someone has a bug they need to track down, they're far more likely to waste cycles on a line like $_=do{local$/;<>}; than one like $_=read_file($file);

    Now let's compare apples to apples:

    use File::Slurp; my $text = read_file( 'filename' );
    vs
    my $text = do { local $/; open my $fh, '<', 'filename' or die "Error opening filename for read - $!"; <$fh> };

    For most programmers, the former looks sane.
