FWIW split ' ', $data is magical in that the ' ' matches any quanitity of whitespace ie spaces, tabs, newlines. Syntactic sugar for \s+ really.
split ' ' and split /\s+/ are not quite the same: 
#!/usr/bin/perl

use strict;
use warnings;

$_ = " foo bar baz ";

my @a = split ' ';
my @b = split /\s+/;

print scalar @a, "\n";
print scalar @b, "\n";
 
__END__
