-=head1 NAME
+# ABSTRACT: Make your attribute(s) tolerant to undef initialization
-MooseX::UndefTolerant - Make your attribute(s) tolerant to undef initialization
+__END__
=head1 SYNOPSIS
the attributes they will not be initialized, effectively behaving as if you
had not provided a value at all.
+You can also apply the 'UndefTolerant' trait to individual attributes. See
+L<MooseX::UndefTolerant::Attribute> for details.
+
+There will be no change in behaviour to any attribute with a type constraint
+that accepts undef values (for example C<Maybe> types), as it is presumed that
+since the type is already "undef tolerant", there is no need to avoid
+initializing the attribute value with C<undef>.
+
=head1 MOTIVATION
I often found myself in this quandry:
$class = My:Class->new(bar => 123);
}
-Or some type of codemulch using ternarys. This module allows you to make
-your attributes more tolerant of undef so that you can keep the first
+Or some type of codemulch using ternary conditionals. This module allows you
+to make your attributes more tolerant of undef so that you can keep the first
example: have your cake and eat it too!
=head1 PER ATTRIBUTE
L<Moose::Meta::Method::Constructor>, not L<Moose::Meta::Attribute>. The good
news is that this is expected to be changing shortly.
