Withdrawn Proposals

These proposals have been withdrawn by their authors or superseded by an alternative proposal that has been accepted by TC39

• lexical scope (dherman)
• Functions
  • shorter function syntax, for defining and (or possibly only) expressing functions concisely (arv). arrow function syntax is the accepted short function proposal

• Classes, Exemplars, Inheritance
  • class operator
  • classes (cormac)
  • classes as sugar (markm)

• Modules - the following are alternative module proposal that were considered prior to accepting modules and related proposal
  • (modules harmonic, (ihab_awad) temporary placeholder)
  • modules primordials
  • modules emaker style
  • modules packages

• Private Name alternatives and extensions
  • Private Names with parallel scoped lexical declarations (allen)
  • Instance Variables work in conjunction with Private Names to provide strong encapsulation/information hiding.

• Proxies: The following are all strawmen intended to patch the original proxies, but are now superseded by direct_proxies:
  • function proxy prototype, enabling function proxies to specify a custom prototype object (dherman)
  • proxy derived traps, derived getPropertyDescriptor and getPropertyNames traps (tomvc)
  • handler access to proxy, giving Proxy handlers access to the intercepted proxy (tomvc)
  • proxy set trap, remove a discrepancy between the default set trap behavior of Proxies vs regular ES5 objects (tomvc)
  • derived traps forwarding handler, semantics of the derived traps of the Proxy default forwarding handler (tomvc)
  • proxy drop receiver, dropping the receiver parameter from get and set traps (tomvc)
  • fixed properties, proxies that enforce non-configurable, non-extensible invariants (tomvc)

• JSON
  • JSON path (crock)

• Internationalization support
  • Unicode supplementary characters was accepted instead of these proposal
    • Full Unicode source code: Permit non-BMP characters in source code and hex escapes for non-BMP characters.
    • Support full Unicode in strings: remove all 16-bit Unicode assumptions concerning strings and source code
