| Subject: | RunnableClass subtype is too restrictive |
When making the class 'B5::HelloWorld' runnable as per the example in
the docs, I get:
: [www-data@karene codescraps/mx-run].0$; mx-run -I. B5::HelloWorld ether
Attribute (class) does not pass the type constraint because: Validation
failed for 'MooseX::Runnable::Invocation::RunnableClass' with value

This is because of the definition in MooseX::Runnable::Invocation:
subtype RunnableClass,
as Str,
where { $_ =~ /^[:A-Za-z_]+$/ };
It really ought to accept any valid Moose class:
subtype RunnableClass,
as ClassName,
where { $_->can('does') and $_->does('MooseX::Runnable' };
This is breaking my heart because the app name of my project is 'B5'. :)
