Bug #41191 for MooseX-Types: Bug, or am I failing to get it?

I'm quite sure that this is probably user error, but the following doesn't work for me currently: package MyTypes; use MooseX::Types::Moose qw/ Str /; use MooseX::Types -declare => [qw/ FooType /]; subtype FooType => as Str => where { 1 }; package MyClass; use Moose; use MyTypes qw/FooType/; has foo => ( isa => FooType ); package main; use MyClass; MyClass->new(foo => 'moo'); What am I doing wrong? Cheers t0m

parses to subtype "FooType", as "Str", where { 1 }; because of the fat comma stringifying to the left. You wanted subtype FooType, as Str, where { 1 }; -- Matt S Trout Need help with your Catalyst or DBIx::Class project? Technical Director http://www.shadowcat.co.uk/catalyst/ Shadowcat Systems Ltd.

If you are attached to the '=>' as I am, since it's a bit more visible in my editor (I tend to use tiny fonts so I can see lots of code) you can do: subtype FooType() => as Str .....; and that will also work. I'm adding docs to this effect in the next version and probably will move up the note regarding the '=>' stringification issue so that it's more clear. I realize all the Moose core docs regarding type constraints use this so it's a bit of switch if you are used to one type of syntax. I would welcome any patches or thoughts how to make this 'just work' to smooth the path a bit. Thanks for the bug report.
