New ES6 Constructor Semantics and Usage Examples

Manual super: Alternative Design where subclass constructors do not automatically call superclass constructors

This Gist presents a new design of class-based object construction in ES6 that does not require use of the two-phase @@create protocol.

One of the characteristics of this proposal is that subclass constructors must explicitly super invoke their superclass's constructor if they wish to use the base class' object allocation and initialization logic.

An alternative version of this design automatically invokes the base constructor in most situations.

Solr JOIN

Solr JOINs are a way to enforce document security, as explained by Yonik Seeley at http://lucene.472066.n3.nabble.com/document-level-security-filter-solution-for-Solr-tp4126992p4126994.html

This repository contains an example of a working Solr JOIN based on data in before.json. Permissions per user are embedded in the primary documents like this:

{
    "id": "dataset_3", 
    "perms_ss": [
