NAME
       MooX::late - easily translate Moose code to Moo

SYNOPSIS
          package Foo;
          use Moo;
          use MooX::late;
          has bar => (is => "ro", isa => "Str", default => "MacLaren's Pub");

       (Examples for Moo roles in section below.)

DESCRIPTION
       Moo is a light-weight object oriented programming framework which aims to be compatible
       with Moose. It does this by detecting when Moose has been loaded, and automatically
       "inflating" its classes and roles to full Moose classes and roles. This way, Moo classes
       can consume Moose roles, Moose classes can extend Moo classes, and so forth.

       However, the surface syntax of Moo differs somewhat from Moose. For example the "isa"
       option when defining attributes in Moose must be either a string or a blessed
       Moose::Meta::TypeConstraint object; but in Moo must be a coderef. These differences in
       surface syntax make porting code from Moose to Moo potentially tricky. MooX::late provides
       some assistance by enabling a slightly more Moosey surface syntax.

       MooX::late does the following:

       1.  Supports "isa => $stringytype".

       2.  Supports "does => $rolename" .

       3.  Supports "lazy_build => 1".

       4.  Exports "blessed" and "confess" functions to your namespace.

       5.  Handles certain attribute traits. Currently "Hash", "Array" and "Code" are supported.
           This feature requires MooX::HandlesVia.

           "String", "Number", "Counter" and "Bool" are unlikely to ever be supported because of
           internal implementation details of Moo. If you need another attribute trait to be
           supported, let me know and I will consider it.

       Five features. It is not the aim of "MooX::late" to make every aspect of Moo behave
       exactly identically to Moose. It's just going after the low-hanging fruit. So it does five
       things right now, and I promise that future versions will never do more than seven.

       Previous releases of MooX::late added support for "coerce => 1" and "default => $nonref".
       These features have now been added to Moo itself, so MooX::late no longer has to deal with
       them.

   Use in Moo::Roles
       MooX::late should work in Moo::Roles, with no particular caveats.

          package MyRole;
          use Moo::Role;
          use MooX::late;

       Package::Variant can be used to build the Moo equivalent of parameterized roles.
       MooX::late should work in roles built with Package::Variant.

          use Package::Variant
             importing => [ qw( Moo::Role MooX::late ) ],
             subs      => [ qw( has with ) ];

   Type constraints
       Type constraint strings are interpreted using Type::Parser, using the type constraints
       defined in Types::Standard. This provides a very slight superset of Moose's type
       constraint syntax and built-in type constraints.

       Any unrecognized string that looks like it might be a class name is interpreted as a class
       type constraint.

   Subclassing
       MooX::late is designed to be reasonably easy to subclass. There are comments in the source
       code explaining hooks for extensibility.

BUGS
       Please report any bugs to <http://rt.cpan.org/Dist/Display.html?Queue=MooX-late>.

SEE ALSO
       "MooX::late" uses Types::Standard to check type constraints.

       "MooX::late" uses MooX::HandlesVia to provide native attribute traits support.

       The following modules bring additional Moose functionality to Moo:

       ·   MooX::Override - support override/super

       ·   MooX::Augment - support augment/inner

       MooX allows you to load Moo plus multiple MooX extension modules in a single line.
