E4X is more than just data production, though. It added a number of accessors/syntax for handling XML elements, many of which can be the LHS of an assignment: expr..ident // descendant selection expr.@ident // attribute selection expr.* // All-children selection expr.(filter) // Filtering a set, with an implicit 'with' @ident // At least within a filter, attribute selection expr.var::ident // Using the namespace in var, descendant selection In combination, they provide some concise ways of manipulating document-free XML nodes, though with large number of downsides that probably aren't worth covering in detail, here. It might be worth considering bringing some of those constructs back in a more generic and future-proof fashion in future versions of ECMAScript. Or it might instead be worth considering allowing quasis to be the LHS of an assignment, which would be useful and could then cover more e4x use cases.
