Hi Monks,

I have a lot (30 94 and growing) of MooseX::Getopt based scripts inheriting from a single role (My::App). My::App includes quite a few getopt-enabled switches which don't make sense in some of the scripts which inherit from it. The result is that when the user runs script --help, they get a page and a half of options which are irrelevant.

I can suppress some options from a script by adding following to the attribute declarations in the inheriting script: 

has( "+$_", traits => ['NoGetopt'] ) for qw<fast_db html_output japane
+se_wts debug_soap lease_tolerance>;

This is effective, but not pretty, and since I have so many classes which use it, it would be nice to put it into a sub in a shared package. My::App seems like the logical choice, but:

has '+attr' is not supported in roles ...

Which is fine with me, but I'm calling this in a class, it's just that Moose thinks I'm calling it in a role. has isn't a method, so I can't use my package to tell Moose that it's being called from a role. It looks like has is using caller to see where it's being called from.

So what do people suggest? Should I:

  1. Put the 'disable_getopt_attribute' code in a different (new) package (which will probably never contain anything else)
  2. Try to work out how to trick has into running in a role
  3. Cut and paste the ugly code in all my classes

What do you think?
