when <circular> printing does not show the number of item in the array
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?
Because it is useful when debugging to know how many items are in the array. related conversation: https://discord.com/channels/592103645835821068/592106336838352923/1251933620214693978
