Re: Moose and exceptions

in reply to Moose and exceptions

This question got answered in #moose on IRC, but just so that Perlmonks has the answer, here you go.

The conflict is in the Moose export &with and the Error export &with. There are a couple of solutions possible:

• Since Moose uses Sub::Exporter it is possible to rename &with in the export, like so:

  package Foo::Role; 
  use Moose::Role; 
  
  package Foo; 
  use Moose with => { -as => "moose_with" }; 
  use Error qw(:try)
  moose_with("Foo::Role"); 
  
  Foo->does("Foo::Role") # returns true
  

• Or, use a different Exception module, Exception::Class is an excellent choice and known to work work just fine with Moose.

It's nice to see the flexibility of the Moose. But, imho, that kind of change in the interface, will affect the maintainability of the code.

Probably the use of the Exception::Class will be a better approach.

I can take no credit, we are simply riding on the shoulders of Sub::Exporter.

But, imho, that kind of change in the interface, will affect the maintainability of the code.

I completely agree, this is a case of "just cause you can do it, doesn't mean you should".
