Dear Perl Monks,
I am trying to use the new MooseX::Declare syntax, in conjunction with Moose subtypes.
Here is my code:
use strict;
use v5.10;
use MooseX::Declare;
use Moose::Util::TypeConstraints;
subtype 'PositiveInt'
=> as 'Int'
=> where { $_ > 0 }
=> message { "Number '$_' is not positive" };
class BankAccount {
use MooseX::StrictConstructor;
has balance => ( isa => 'Int', is => 'rw', default => 0 );
method deposit ( PositiveInt :$amount ) {
$self->balance( $self->balance + $amount );
}
}
my $a = BankAccount->new( balance => 100 );
$a->deposit( amount => 50 );
say $a->balance;
This code gives the following error when executed:
'PositiveInt' could not be parsed to a type constraint - maybe you nee
+d to pre-declare the type with class_type at /home/moose/perl5/lib/pe
+rl5/MooseX/Declare/Syntax/MethodDeclaration.pm line 40
I haven't been able to find a class_type() method in the MooseX::Declare documentation.
Could someone enlighten me about what should be done ?
Thank you in advance

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

are good places to start.
