SYNOPSIS

            

              
              
no underscore; # outlaws $_
while(<>){ # croaks here!
  print;
}
use underscore;
# back to normal
            
          

DESCRIPTION

This module detects the use of global $_ and croaks. If you want it to carp or confess, simply

            

              
              
no underscore 'carp';
            
          

You can also use your custom subroutine like

            

              
              
no underscore sub { ... }
            
          

You can also customize the error message like

            

              
              
no undersocore 'croak', 'I said not to use $_'!
            
          

EXPORT
