Resolution Duplicate
Environment

Apple Swift version 5.3 (swiftlang-1200.0.25.2 clang-1200.0.27.1)
Target: x86_64-apple-darwin19.6.0

Also exists with Swift 5.2 but the error is less helpful (it's an "type is ambiguous" error there).

  • SR-12991 Type checker doesn't take context from " as " - Examples in Key Path Expressions as Functions proposal don't compile

Issue Description:

KeyPaths can be used where functions are expected. But this doesn't work with the as operator.

let f: (Point) -> Int = \Point.x

{code:swift|title=This doesn't}
let f = \Point.x as (Point) -> Int
