-DESCRIPTION
-    Data::Perl is a collection of classes that wrap fundamental data types
-    that exist in Perl. These classes and methods as they exist today are an
-    attempt to mirror functionality provided by Moose's Native Traits. One
-    important thing to note is all classes currently do no validation on
-    constructor input.
-
-    Data::Perl is a container class for the following classes:
-
-    *   Data::Perl::Collection::Hash
-
-    *   Data::Perl::Collection::Array
-
-    *   Data::Perl::String
-
-    *   Data::Perl::Number
-
-    *   Data::Perl::Counter
-
-    *   Data::Perl::Bool
-
-    *   Data::Perl::Code
-
-ALPHA API
-    The API provided by these modules is as of now considered alpha and
-    undecided. The API WILL change. If you are writing code that you will
-    not touch again for years, do not use this until this warning is
-    removed.
-
-PROVIDED FUNCTIONS
-    Data::Perl exports helper constructor functions to interface with the
-    above classes:
-
-    *   hash(key, value, ...)
-
-        Returns a Data::Perl::Collection::Hash object initialized with the
-        optionally passed in key/value args.
-
-    *   array(@args)
-
-        Returns a Data::Perl::Collection::Array object initialized with the
-        optionally passed in values.
-
-    *   string($arg)
-
-        Returns a Data::Perl::String object initialized with the optionally
-        passed in scalar arg.
-
-    *   number($arg)
-
-        Returns a Data::Perl::Number object initialized with the optionally
-        passed in scalar arg.
-
-    *   counter($arg)
-
-        Returns a Data::Perl::Counter object initialized with the optionally
-        passed in scalar arg.
-
-    *   bool($arg)
-
-        Returns a Data::Perl::Bool object initialized with the truth value
-        of the passed in scalar arg.
-
-    *   code($arg)
-
-        Returns a Data::Perl::Code object initialized with the optionally
-        passed in scalar coderef as an arg.
-
-THANKS
-    Much thanks to the Moose team for their work with native traits, for
-    which much of this work is based.
