Reflection is not able to wrap/unwrap an object from his interface

[Dracks]

Describe the bug

Code: https://vosca.dev/p/d563469814

struct Something {
	count int = 0
}

struct StrWithSomething {
	mut:
	something &Something = unsafe{nil}
}

interface Object {}

fn main(){
	s := &Object(Something{})
	mut str_with := StrWithSomething{}
	$for field in StrWithSomething.fields {
		str_with.$(field.name) = s
	}
	println(str_with)
}

Expected Behavior

In this case, s should be unpacked from the Object interface, to assign correctly the original struct to the property.

Current Behavior

is assigning the C Object (representing the V interface) directly to the field, not detecting the change of type on the progress.

The output field, you get allways a count != 0 (as it's pointing to the wrong place in memory)

Output:

StrWithSomething{
    something: &Something{
        count: 340525024
    }
}

Reproduction Steps

Simply run the program, and you will see it.

Possible Solution

when doing the reflection, V should detect the type of the field at which are we accessing, and process it as normal code

[felipensp]

I don't get it. If you do str_with.something = s it produces:

cannot assign to `str_with.something`: expected `&Something`, not `&Object`

Why using comptime reflection should it works?

[Dracks]

ok, I was thinking I tested that case and was working. I see that it's not working, It will be good at least to raise an error if v doesn't wish to be able to handle. I think will be really usefull to be able to do the cast/wrap, correctly.
