Confusing error message when trying to initialize an anonymous struct with {}

[zeozeozeo]

Describe the bug

Running the code below, the compiler produces a confusing error message and a completely unrelated message just after.

Reproduction Steps

struct AStructName {
	foo int
	anon struct {
		bar int
	}
}

fn main() {
	s := AStructName{5, {}}
	println(s)
}

Expected Behavior

An error that says to use struct {} to initialize the anonymous struct.

Current Behavior

test.v:9:22: error: `{}` can not be used for initialising empty structs any more. Use `_VAnonStruct1{}` instead.
    7 |
    8 | fn main() {
    9 |     s := AStructName{5, {}}
      |                         ~~
   10 |     println(s)
   11 | }
test.v:9:22: error: `map{  }` (no value) used as value
    7 |
    8 | fn main() {
    9 |     s := AStructName{5, {}}
      |                         ~~
   10 |     println(s)
   11 | }

Possible Solution

Change the error message to suggest using struct {} to initialize the embedded struct.

Additional Information/Context

The code in the error message does work, which is a little bit weird:

struct AStructName {
	foo int
	anon struct {
		bar int
	}
}

fn main() {
	s := AStructName{5, _VAnonStruct1{}}
	println(s)
}

the above compiles and runs, but it probably shouldn't (since _VAnonStruct1 is a type defined by the compiler). Could be related to a different issue.
