Data::Object::Role::Tryable

=cut

=head1 ABSTRACT

Tryable Role for Perl 5

=cut

=head1 SYNOPSIS

  package Example;

  use Moo;

  with 'Data::Object::Role::Tryable';

  package main;

  use routines;

  my $example = Example->new;

=cut

=head1 DESCRIPTION

This package provides a wrapper around the L<Data::Object::Try> class which
provides an object-oriented interface for performing complex try/catch
operations.

=cut

=head1 METHODS

This package implements the following methods:

=cut

=head2 try

  try(CodeRef | Str $method) : InstanceOf['Data::Object::Try']

The try method takes a method name or coderef and returns a
L<Data::Object::Try> object with the current object passed as the invocant
which means that C<try> and C<finally> callbacks will receive that as the first
argument.
