Data::Object::Cast

ABSTRACT

Data Type Casting for Perl 5

SYNOPSIS

  package main;

  use Data::Object::Cast;

  local $Data::Object::Cast::To = 'Test::Object';

  # Data::Object::Cast::Deduce([1..4]); # Test::Object::Array

DESCRIPTION

This package provides functions for casting native data types to objects and the reverse.

LIBRARIES

This package uses type constraints from:

Types::Standard

FUNCTIONS

This package implements the following functions:
