Please why does this throw an error?

[T:\tmp]cat try.pl
use strict;
use warnings;

foo("Hello World");
exit;
{
  my $bar = 1;

  sub foo
  {
    my $a = shift;
    print "$bar $a\n";   # <== line 12
    return;
  }

}

[T:\tmp]try.pl
Use of uninitialized value in concatenation (.) or string at try.pl
line 12.
 Hello World

So $bar is private to foo - but you can't initialise it?

TIA
