Issue Description:
The following code crashes the compiler.
struct Foo { let foo: Int }
struct Bar { let bar: String }
Bar(bar: "Hello!")[keyPath: \Foo.foo]The crash:
TYPE MISMATCH IN ARGUMENT 0 OF APPLY AT expression at
RangeText="Bar(bar: "Hello!")[keyPath: \Foo.foo]"
Ideally this is a normal compiler error, instead.
