Why doesn't the 'while' loop slurp the data too?
Because the filehandle is only evaulated in a scalar context, so you'll only get one line per iteration. Whereas a foreach loop evaluates the filehandle in a list context which produces the list which it iterates over. Another thing to be aware of is that if you're iterating over a filehandle in a while loop perl will auto-magically stick a defined test around your condition e.g 
while(my $line = <DATA>)
# becomes
while (defined(my $line = <DATA>))

So now if a single 0 is read the loop will continue.
