> local doesn't remove the magic — the variable is still tied in the block

argh you're right, I didn't test what I didn't expect... I would explicitly need to untie the localized var.

package NewStdScalar;
require Tie::Scalar;
 
@ISA = qw(Tie::StdScalar);
 
 
sub FETCH { return ${+shift}++ }
 
package main;
$\="\n";
$,="\t";
 
 
 
tie our $scalar, 'NewStdScalar';
 
sub prsc {print $scalar    };
$scalar=0;
 
prsc();
 
{
  local $scalar=42;
  # untie $scalar;  # uncomment this to make it work
  prsc();
  prsc();
  prsc();
  print $scalar; 
}
 
   
prsc();

Sorry, ATM I'm too tired to look further into the examples you posted, later more.

But I think I will go the simple way to exclude the use of tied variables by throwing a warning. Thx,

Cheers Rolf
