Seeing the syntax in practice brings up some thoughts.

1. The naming scheme for propArrays vs argument accepted in the helper function.
   A) Should the property be plural members but the helper functions be singular addMember and accept a coala-ip instance of person in this instance.
   or
   B) Should any propArray helper functions accept only arrays containing at least 1 coala-ip instance without throwing an error.
   I am partial to the latter.

2. This helps us in the short term gain parity over our schema on the front end and db however I'm not sure it solves the issue fully enough. It seems as though we should migrate all propArrays to the updated syntax for consistency's sake.

Let me know your thoughts.

Ah good catch! I meant to revisit that too. I like B and migrating the other propArrays as well.
