Re^2: Reading a huge input line in parts (Handles multi-digit numbers!)

Could this not be simplified?

sub genBufferedGetNum {
    return sub {
                @buf = do{ local $/ = \10; split ' ', <> };
                return @buf;
    };
}

my $getNum = genBufferedGetNum();

while( my @part  = $getNum->() ) {
  print @part, "\n";
}

I shortened the buffer size for testing purposes

$: cat tb.dat
0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0

Could this not be simplified? And what happens when your buffer size splits a multi-digit number in two? Ie. Run your code against this input: `123 456 789 1` [download] And it produces: `123 456 78 9 1` And doesn't notice that the last number is supposed to be 0. With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday' Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error. "Science is about questioning the status quo. Questioning authority". I'm with torvalds on this In the absence of evidence, opinion is indistinguishable from prejudice.
