"""TS/JS receiver-typed member calls beyond `this.field` (#1630).
|
|
|
|
The #1316 resolver handled `this.injectedField.method()`. This adds two receiver
|
|
tiers whose type is statically known but was previously dropped, so
|
|
`affected <method>` silently under-reported:
|
|
|
|
A. a local `const x = new Foo()` binding, then `x.method()`;
|
|
B. a closure over a type-annotated parameter, `f(x: Foo) => () => x.method()`.
|
|
|
|
Resolution is by receiver type with the single-definition guard; an untyped or
|
|
non-bare-typed receiver produces no edge.
