MooseX::Has::Sugar::Saccharin - Experimental sweetness

version 1.000006

This is a highly experimental sugaring module. No Guarantees of stability.

    use MooseX::Types::Moose qw( :all );
    has name   => rw Str, default { 1 };
    has suffix => required rw Str;
    has 'suffix', required rw Str;

Your choice.

exports:

"ro", "rw", "required", "lazy", "lazy_build", "coerce", "weak_ref", "auto_deref", "bare", "default", "init_arg", "predicate", "clearer", "builder", "trigger"

    bare Str

equivalent to this

    is => 'bare', isa => Str


    ro Str

equivalent to this

    is => 'ro', isa => Str,


    rw Str

equivalent to this

    is => 'rw', isa => Str

this

    required rw Str

is equivalent to this

    required => 1, is => 'rw', isa => Str,

this

    rw Str, required

is equivalent to this

    is => 'rw', isa => Str , required => 1

like "( lazy => 1 , @rest )"

like "( lazy_build => 1, @rest )"

like "( weak_ref => 1, @rest )"

like "( coerce => 1, @rest )"

WARNING:

Conflicts with "MooseX::Types's" "coerce" method

like "( auto_deref => 1, @rest )"

    required rw Str, builder '_build_foo'

is like

    builder => '_build_foo'

see "builder"

see "builder"

see "builder"

Examples:

    default { 1 }
    default { { } }
    default { [ ] }
    default { $_->otherfield }

$_ is localized as the same value as $_[0] for convenience ( usually $self )

Works exactly like default.

This module is not intended to be used in conjunction with
::Sugar or ::Sugar::Minimal

We export many of the same symbols and its just not very sensible.

due to exporting the "coerce" symbol, using us in the same scope as a call to

    use MooseX::Types ....

or
use Moose::Util::TypeConstraints

will result in a symbol collision.

We recommend using and creating proper type libraries instead, ( which will absolve you entirely of the need to use MooseX::Types and MooseX::Has::Sugar(::*)? in the same scope )

the keyword 'default' becomes part of Perl in both these cases:

    use 5.010;
    use feature qw( :switch );

As such, we can't have that keyword in that scenario.
