Can't evaluate struct creation

[kmillikin]

Delve Version: 1.9.1 and Go go version go1.20-pre3 cl/474093167 +a813be86df linux/amd64.

Test case is simple:

package main

import "fmt"

type Options struct {
        WithBreakfast bool
        WithLunch     bool
        WIthDinner    bool
}

func main() {
        x := Options{}
        fmt.Sprintf("%v", x)
}

Set a breakpoint in main and try to evaluate Options{}:

(dlv) break main.go:13
Breakpoint 1 set at 0x49cca4 for main.main() ./main.go:13
(dlv) c
> main.main() ./main.go:13 (hits goroutine(1):1 total:1) (PC: 0x49cca4)
     8:         WIthDinner    bool
     9: }
    10:
    11: func main() {
    12:         x := Options{}
=>  13:         fmt.Sprintf("%v", x)
    14: }
(dlv) call Options{}
> main.main() ./main.go:13 (hits goroutine(1):1 total:1) (PC: 0x49cca4)
Command failed: expression *ast.CompositeLit not implemented

I should be able to evaluate this here, it's on a line just after an identical expression. (The error message is also really cryptic.)
