Description Keith Miller 2020-06-22 19:02:51 PDT 
If a script has a very large JSON payload we currently allocate bytecode to initialize the object proportionally to the size of the object. This is very inefficient since most JSON massive objects are only initialized once. Instead, we should have a bytecode that takes a source position to parse as JSON.
