* Initial implementation
The original test passes but I haven't run any other tests yet, so I
assume the world is now broken.
* Append constructor function construct sigs
Instead of overwriting them
* Grab bag of improvements.
1. Mark @class-tagged functions with Class too.
2. Only gather local type parameters of constructor functions.
3. Remove getJSClassType calls with getDeclaredTypeOfSymbol.
4. Add a couple more failing tests.
getDeclaredTypeOfClassOrInterface now needs to understand prototype
assignment. That's next, I think.
* Prototype assignments work now
1. Binder marks prototype assignments as Class now.
2. Checker merges prototype assignments using the same merge code as for
functions and their declarations. No more intersections.
Many fewer failing tests now.
* Mark prototype-property assignments as Class
Even if there are no this-property assignments in them. (Then why are
you using a class?).
* Simplify getJSClassType, remove calls to its guts
It's probably not needed because now it's just a conditional call to
getDeclaredTypeOfSymbol, and I think most callers already know whether
they have a JS constructor function beforehand.
* isJSDocConstructor doesn't need to check prototype anymore
Because all the properties are merged during getDeclaredTypeOfSymbol.
* outer type parameter lookup follow prototype assignment
* this-type and -expression support in ctor funcs
Pretty cool!
* Fix remaining tests
* Fix minor lint
* Delete now-unused code
* Add class flag to nested class declarations
Also remove old TODOs
* Add helpers that understand constructor functions
* getEffectiveConstructSignatures gets construct signatures from type, and
call signatures from constructor functions if there are no construct
signatures.
* getEffectiveConstructSignatureReturnType gets the "JS Class type" for
constructor functions, and the return type of signatures for all other
declarations.
This is a first step toward making constructor functions have construct
signatures instead of call signatures, which will also contribute to
fixing instantiation of generic constructor functions, which is basically
broken right now.
Note that the baselines *improve* but, because of the previously
mentioned generic problem, are still not correct. Construct signatures
for constructor functions and generic constructor functions turns out to
be an intertwined problem.
* Correct correct originalBaseType
And, for now, return anyType for generic constructor functions used as
base types. Don't give an incorrect error based on the function's return
type, which is usually void.
* Add error examples to tests
* Add construct signatures instead of getEffective* functions
* Fix typo in baseline
* Remove pesky newline
I thought I got rid of it!
* Test of constructor tag on object literal method
It doesn't work, and shouldn't in the future, because it's a runtime
error.
