NAME
    MooseX::InlineTypes - declare type constraints and coercions inline with
    coderefs

SYNOPSIS
       use v5.14;
   
       package Document {
          use Moose;
          use MooseX::InlineTypes;
          has heading => (
             traits  => [ InlineTypes ],
             is      => "ro",
             isa     => sub { !ref($_) and length($_) < 64 },
             coerce  => sub { sprintf("%s...", substr($_, 0, 60)) },
          );
       }

DESCRIPTION
    This module provides an attribute trait that allows you to declare Moose
    type constraints and coercions inline using coderefs, a bit like Moo,
    but not quite.

  "isa => CODEREF"
    This is a coderef which returns true if the value passes the type
    constraint and false otherwise.

  "coerce => CODEREF"
    This is a coderef which takes the uncoerced value and returns the
    coerced value.

  "coerce => ARRAYREF"
    This allows you to specify several different coercions from different
    types:

       isa    => "ArrayRef",
       coerce => [
          Str     => sub { split /\s+/, $_ },
          HashRef => sub { sort values %$_ },
          CodeRef => sub { my @r = $_->(); \@r },
       ],

    The order of coercions is significant. For example, given the following
    the "Int" coercion is never attempted, because "Any" is tried first!

       coerce => [
          Any     => sub { ... },
          Int     => sub { ... },
       ],

    Note that "coerce => CODEREF" is really just a shorthand for "coerce =>
    [ Item => CODEREF ]".

    Attributes declared with the MooseX::InlineTypes trait do still support
    the "normal" Moose "isa" and "coerce" options, though it should be noted
    that "isa=>CODE, coerce=>1" makes no sense and Moose will give you a
    massive warning!

EXPORT
    "InlineTypes"
        This is an exported constant so that you can write:

           traits  => [ InlineTypes ],

        Instead of the more long-winded:

           traits  => [ "MooseX::InlineTypes::Trait::Attribute" ],

    "-global"
        If you do this:

           use MooseX::InlineTypes -global;

        Then the InlineTypes trait will be applied automatically to *all*
        your attributes. (Actually only to those attributes declared using
        "has". Attributes added via Moose meta calls will be unaffected.)

        Don't worry; it's not really global. It's just for the caller.

  Usage with MooseX::Types
    Here's the example from the SYNPOSIS rewritten using MooseX::Types:

       use v5.14;
   
       package Document {
          use Moose;
          use MooseX::InlineTypes -global;
          use MooseX::Types qw( Str is_Str );
          has heading => (
             is      => "ro",
             isa     => sub { is_Str($_) and length($_) < 64 },
             coerce  => [
                Str, sub { sprintf("%s...", substr($_, 0, 60)) },
             ]
          );
       }

    Note that MooseX::Types exports "is_X" functions for each type which can
    be useful inside the "isa" coderefs.

    With coercion arrayrefs, beware the magic quoting power of the fat
    comma!

HISTORY
    This was originally a patch for MooseX::AttributeShortcuts until Matt S
    Trout (cpan:MSTROUT) convinced me to rewrite it independently of that.
