So you can't do this with your own defines as the resource?
I have various define calls like this:
users::normal { bob: id => 107, email => 'b...@bob.com' }
What I'm looking to do is collect all the emails into an array or
something so I can use them in a template.
I thought maybe I could make a define that does an array append or
something?
It sounds from what people are saying like there really isn't a
reasonable way to do this yet?
