Is this a shortcut of sorts to memory reference pointers? It feels a
little bit like a string_map function. Scripters have a hard time
molding that problem.
I think it's interesting that in some of the newer languages, the
simplest constructs are abstract ideas that similarly describe the
most systemically atomic memberships: generics, collections, objects.
Scripting is built around flexibility, so everything is everything;
ie, in JavaScript, everything is a generically collectionable object
(consider closures and anonymous functions); once you figure out how
to build classes and constructors, it's like gravy. C#, php, java,
python, etc...
"Simplicity" points at something different in strong-typed languages
than it does in soft-typed interpreted languages.
