NAME

Lazy::Bool::Cached - Boolean wrapper lazy with memoize

SYNOPSIS

  use Lazy::Bool::Cached;

  my $result = Lazy::Bool::Cached->new(sub{  
  	# complex boolean expression
  });

  #...
  if($result) { # now we evaluate the expression
	
  }

  if($result) { # do not evaluate again. it is cached.

  }
  
 # Using this module you can play with lazy booleans. 

 # With expressions '&', '|' and '!' you can delay the expression evaluation until necessary.
