* Support some late-bound special property assignments
* Integrate PR feedback
* PR feedback
* Enable declaration on core tests
* Specialize type of binary expression used for late binding, speculative fix to navigation bar, merge check and type for elem/property accesses
* Add test showing current nav bar behavior (specifically the lack thereof)
* Bind non-expando property assignments at toplevel
Previously, only property assignments with expando initialisers were
bound in top-level statements. Now, all property assignments are bound.
This requires a matching change in the checker to make sure that these
assignments remain context sensitive if their valueDeclaration is a
'real' declaration (ie a non assignment-declaration).
* Add baselines for new test
* Allow special property assignments in TS
But only for functions and constant variable declarations initialised with
functions.
This specifically excludes class declarations and class expressions,
which differs from Javascript. That's because Typescript supports
`static` properties, which are equivalent to property assignments to a
class.
* Improve contextual typing predicate
Don't think it's right yet, but probably closer?
* More fixes.
The code is still fantastically ugly, but everything works the way it
should.
Also update baselines, even where it is ill-advised.
* Cleanup
* Remove extra whitespace
* Some kind of fix to isAnyDeclarationName
It's not done yet.
Specifically, in TS:
Special property assignments are supposed to be declaration sites (but not all
top-level assignments), and I think I
got them to be. (But not sure).
In JS:
Special property assignments are supposed to be declaration sites (but not all
top-level assignments), and I'm pretty sure ALL top-level assignments
have been declaration sites for some time. This is incorrect, and
probably means the predicate needs to be the same for both dialects.
* Add fourslash and improve isAnyDeclarationName
Now JS behaves the same as TS.
* Cleanup from PR comments
