when <circular> printing does not show the number of item in the array

[Eliyaan]

Describe the bug

When printing a struct with an array that prints as [<circular>], it does not show the number of items in the array.

Reproduction Steps

 struct Bar {
 mut:
         children []Bar
 }
 
 fn main() {
         mut a := Bar{}
         a.children << Bar{}
         a.children << Bar{}
         println(a)
         println(a.children)
}

Expected Behavior

Bar{
    children: [<circular>, <circular>]
}
[Bar{
    children: []
}, Bar{
    children: []
}]

Current Behavior

Bar{
    children: [<circular>]
}
[Bar{
    children: []
}, Bar{
    children: []
}]

Possible Solution

No response

Additional Information/Context

And maybe instead of <circular> the print could show <circular?> as it does not know whether or not it is circular.

The problem it is reporting is circular references. Why would you need to know how many were in the same array?

[Eliyaan]

Because it is useful when debugging to know how many items are in the array. related conversation: https://discord.com/channels/592103645835821068/592106336838352923/1251933620214693978
