About this Directory

This ‘strawman’ namespace is intended to contain proposals for the “ES-Harmony” language that are not yet approved harmony proposals, and to clearly separate them from the legacy ES4 pages.

• Catch-alls
  • catchalls The original catch-all proposal, withdrawn in favor of proxies
  • proxies An alternative catch-all proposal
• classes
• concurrency or the TC39 committee’s response to threads suck
• name property of functions
• function to string – greater specification for problematic Function.prototype.toString
• generators, but better than the Pythonic form in JS1.7 – those do not compose well
• lambdas, real lambda expressions that satisfy Tennent Correspondence Principles
• expression closures, for defining and expressing functions with single-expression-as-return-value bodies
• lexical scope
• modules
  • modules_primordials
  • modules_emaker_style
  • modules_packages
  • simple_modules (and simple_modules_examples)
• names
• return to label
• types
• value types, for first-class number-like objects with operators and (we hope) literal syntax
• weak references with contraints, see Ephemerons
• encapsulated hashcodes based on discussion among awb, markm, and brendan, 30 july 2009
• byte arrays, based on emerging webapi discussions and implementations
• typed arrays, similar to the above byte arrays, as originally defined by webgl
• random-er, or a better (cryptographically strong) random number generator (see https://bugzilla.mozilla.org/show_bug.cgi?id=322529)
• more Math fun, see Alistair Braidwood's message
• object initialiser extensions, for method (like get and set), freezing, and other common declarative forms
  • see destructuring for “record extension and row capture” via ... – this may need its own proposal page
• versioning, the full versioning of script tag content and whole-frame/window object model monty
• string interpolation, quasis, and quasis-alt for string desugaring that would allow experimentation with string interpolation and richer macros. free-vars alpha-rename
• ast, a parser built into conforming Harmony implementations which returns a standard abstract syntax tree
• egal, an identity-testing operator inspired by Henry Baker’s egal
• system, a place to put powerful objects provided by the embedding without having to introduce names into the global scope every time.
