Tie::Hash::Constant - make a hash return a constant for all its members
use Tie::Hash::Constant; tie my %always_pie, 'Tie::Hash::Constant' => 'PIE!'; $always_pie{food} = "salad"; print "My favourite food is $always_pie{food}\n"; # prints "My favourite food is PIE!" print "There is no $always_pie{spoon}\n"; # prints "There is no PIE!\n"; !!!
Tie::Hash::Constant allows you to define a constant to be returned as all values contained within a hash.
It has marginal use as a debugging tool.
