Sure. I can describe the state of most issues as named by the proposals
page, I think. Some of the proposals have sort of no-longer-sensible
names so I'm going to use the proposals page as a rough guide and name
the things that have seemed, in my work, to be separate "features" of
the RI.
Implemented, may have bugs:
- classes and interfaces
- namespaces
- pragmas
- let, const, let-const
- iterators
- enumerability control
- type expressions / definitions / annotations
- runtime type checks ("standard mode")
- nullability
- destructuring assignment
- slice syntax
- hashcode
- catchalls
- map & vector
- date & time improvements
- meta objects
- static generics
- string trim
- typeof
- globals
- expression closures
- name objects
- type operators (is / to / cast / wrap)
Implemented and partly working, but still in flux / work to do:
- inheritance checking
- strict mode
- type parameters
- structural types
- numbers & decimal
- getters & setters (structural part is incomplete)
- packages
Partially implemented / not yet working:
- program units
- generic function
- updates to unicode
- updates to regexps
Unimplemented:
- generators
- tail calls
- triple quotes
- stack inspection
- reformed with
- resurrected eval (eval exists but may be wrong)
- help for the argument object
- "this function" / "this generator"
In my mind the "high priority" deficits where I actually know what to do
are:
- extending strict mode
- extending the part of the definer that checks inheritance
The remaining issues on my list all involve some spec/discussion work
(units and packages, type parameters, structural typechecks, tail calls,
reformed rules for with/this/eval/arguments)
