Scalar::Andand - Guarded method invocation.
Scalar::Andand lets us write:
$phone = Location->find('first', name => 'Johnson' )->andand->phone
And get a guarded method invocation or safe navigation method. This snippet performs a
find on the Location class, then calls
phone to the result if the result is defined. If the result is not defined, then the expression returns false without throwing an exception.
This module doesn't export anything to your namespace, but it does add a universal method andand, which is a far graver sin.

You have to include the module in every package where you use the magic
andand method, or else it doesn't work on undefined values.
This module contains more magic than what is responsible, don't be surprised by weird bugs.
Note that this module was intended as a proof of concept. The author has never used it in production code, nor is he planning to do so. YMMV.
Please report any bugs or feature requests to
