 ### Fixes
 
+- In R, a call like `c(1, 2)` is no longer linked to a data variable that happens to share a base function's name, since R skips non-function bindings when it looks up a call. Before, ggplot2's facet tests bound `c <- data_frame(b = 3)`, and every `c(…)` call in those files pointed at that data frame. Functions built by a factory, like ggplot2's `geom_point <- make_constructor(…)`, still resolve.
 - In Swift, a call to an overloaded method now reaches the overload whose argument labels it spells, with defaulted parameters optional. Before, only the argument count was compared. Alamofire's `self.tableView(tableView, numberOfRowsInSection:)` inside another `tableView` overload linked to itself, and `cancel(optionallyProducingResumeData:)` linked to `cancel(producingResumeData:)`.
 - A Dart `extension on X { … }` with no name is no longer mistaken for the type `X`, and its members are reachable only inside the file that declares it, as in Dart. Before, bloc's linter linked analyzer's `Token` and Dart's `Uri` to small extension blocks, and every flutter_test `find.text(…)` call linked to a `text` getter on another example's `TaskStatus`.
 - In Java, a bare type name now resolves only to a type in reach. That is a type in the same package, one imported by name or with `.*`, or a nested type used from inside its owner, from a subclass (anonymous classes included), or written through its owner as in `Outer.Inner`. A constructor no longer stands in for its class, and an enum constant is reached by bare name only inside its enum, in a `case` label, or through a static import. Before, retrofit's `new Retrofit.Builder()` linked to `RequestFactory.Builder`, halo's micrometer `Counter` to its own `Counter` class, and jsoup's `java.lang.Class<?>` to a nested selector class.
