I think this would be useful:
Get an enumerable property:
var x = myDict [*enumerable] .someName;
var x = myDict [*enumerable] [someVariable];
Call the non-enumerable .toString():
var x = myDict [*!enumerable] .toString();
Distinguish between owned and inherited properties:
var x = myDict [*own] .someName;
var x = myDict [*!own] .toString();
Loop through a subset:
for (var x in myDict [*own]) {...}
The syntax is meant to suggest that we pick a subset, such as
all the enumerable properties, and then pick a property from
this subset.
Here's an alternate syntax, more logical but less readable
in my opinion:
var x = myDict .:enumerable .someName;
var x = myDict .!enumerable .toString();
