in thread The difference between my and local

I am getting following error, when I use strict and use $tt instead of $a My Code:-

use strict;
my $tt = 3.14159;
{
  local $tt = 3;
  print "In block, \$tt = $tt\n";
  print "In block, \$::tt = $::tt\n";
}
print "Outside block, \$tt = $tt\n";
print "Outside block, \$::tt = $::tt\n";
