[chef-dev] Resource attribute green fields experiment

[Noah Kantrowitz < >]

I was distracted today and wanted to play with some ideas for how resource 
properties (née resource attributes) might look if we had no compat 
requirements at all. https://gist.github.com/coderanger/0e7116e656f6f6acfa18 ;
is what I came up with. To try and avoid stealing his thunder, I would like 
to state clearly that John Keiser has code which looks very similar to this 
but is totally independent, we just both wrote similar stuffs. So basically 
don't apply any shortcomings from this to his work :-) Would love any 
feedback on this. Some notable compat issues I'm ignoring: this moves the 
validation logic so any custom _pv* monkey patches would fail, it allows 
setting nil as a property value (which is planned to be phased in over the 
path to Chef 13), default values do not get written to the instance variable 
of the same name on the resource ever. All of those could be fixed and in 
fact John's version of this idea is far more complete than mine. Still, 
wanted to share in the interests of idea pollination.
