=head1 NAME

Scalar::Andand - Guarded method invocation.

=head1 VERSION

Version 0.04

=head1 SYNOPSIS

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 C<find> on the Location class, then calls C<phone> to the result if the result is defined. If the result is not defined, then the expression returns false without throwing an exception. 

=head1 EXPORT

This module doesn't export anything to your namespace, but it does add a universal method andand, which is a far graver sin.

=head1 AUTHOR

=head1 BUGS

You have to include the module in every package where you use the magic C<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 C<bug-scalar-andand at rt.cpan.org>, or through
the web interface at L<http://rt.cpan.org/NoAuth/ReportBug.html?Queue=Scalar-Andand>.  I will be notified, and then you'll
automatically be notified of progress on your bug as I make changes.
