Still need to make some issues in the repo about spec problems, also the spec is only partly accepted so no async parts.

as much as I like the code and effort, i guess that dealing with stage 2 might not be a best idea. (there was e.g. a split with stage 2 implementation of decorators being implemented once…).

iʼm not really against it but i would advise to wait for at least stage 3 proposal.

This proposal is already at stage 3, although it's not mentioned in the repo itself, but it is listed here: https://github.com/tc39/proposals under stage 3 and babel/proposals#85 (comment) this is where I got the fact that async is not stage 3.

I think some stuff will still change (I even found some spec issues) but I'm up for updating the code as the proposal gets updated.

The bytecode impl is gonna be hell isn't it...

Great stuff! Once again we have better test coverage than test262 😄

Addressed most of the comments, just not sure what would be best in the Optional reference case

@davidot
LibJS: Clarify more errors in test-common
87bfbc9 
Without a message these just show 'ExpectationError' even if the check
has multiple steps.
@davidot
LibJS: Add custom details to toBe{True, False} shown on failure
8402726 
Any test with multiple expect(...).toBe{True, False} checks is very hard
to debug.
@davidot
LibJS: Add SuppressedError{, Prototype, Constructor}
92e69a6
@davidot
LibJS: Add an initialize binding hint to all initialize_binding methods
6d359bf 
This will allow us to specify things like SyncDispose and perhaps
AsyncDispose in the future.
@davidot
LibJS: Add Symbol.dispose
7a5e042
@davidot
LibJS: Add using declaration support, RAII like operation in js
349110d 
In this patch only top level and not the more complicated for loop using
statements are supported. Also, as noted in the latest meeting of tc39
async parts of the spec are not stage 3 thus not included.
@davidot
LibJS: Add using declaration support in for and for of loops
d39a4ca 
The using declarations have kind of special behavior in for loops so
this is seperated.
@davidot
LibJS: Add DisposableStack{, Prototype, Constructor}
04b432a 
Since the async parts of the spec are not stage 3 at this point we don't
add AsyncDisposableStack.

Done and also quickly checked all the commit do build and run test-js since I had some refactor trouble.
