NAME ^

Tie::FlipFlop - Alternate between two values.

SYNOPSIS ^

    use Tie::FlipFlop;

    tie my $flipflop => Tie::FlipFlop => qw /Red Green/;

    print  $flipflop;      # Prints 'Red'.
    print  $flipflop;      # Prints 'Green'.
    print  $flipflop;      # Prints 'Red'.

DESCRIPTION ^

Tie::FlipFlop allows you to tie a scalar in such a way that refering to the scalar alternates between two values. When tying the scalar, exactly two extra arguments have to be given, the values to be alternated between.

Assigning to the scalar leads to a fatal, but trappable, error.
