<br>
#lang typed/racket<br>
<br>
(: foo ([#:k Any] -> Integer))<br>
(define (foo #:k [s #f]) 0)<br>
<br>
(let: ([i : Integer (foo #:k #t)]) i)<br>
<br>
The reason is that the expansion of keyword applications generates a<br>
name to use for the function (here `foo`), and it uses<br>
`syntax-local-infer-name` to get the name to use. Unfortunately, in<br>
this case, it produces `i`, an identifier which has an extra syntax<br>
property saying that `i` is an `Integer`. Of course, `foo` isn't an<br>
integer, it's a function, and so we get a type error.<br>
<br>
I don't see why the inferred name is the right choice here -- there's<br>
no connection between `i` and the name of the function. I can just<br>
change this to use a fresh name, but I thought I'd ask first.<br>
