Hi,

I would like to turn a multiline string that looks like

1 A
2 B
[download]

into a hash that looks like

{
  1 => "A",
  2 => "B", 
}
[download]

And I tought this was easy enough, however to my surprise this does not work:

use strict; 
use Data::Dumper;

my $s = "1 A\n2 B\n"; 

my %h =map { $1 => $2 } $s =~ /(\d+)\s+(\S+)/mg;
print Dumper(\%h);
[download]

It produces

$VAR1 = {
          '2' => 'B'
        };
[download]

Could someone please explain to me what is going on here?

Many thanks!
