Hi,
In all the cases I've seen, calling repr on a .NET type ends up calling

Hi, me again!
I realise the error seems logical enough, but it isn't right. The
documentation for Vector3 specifies that the fields X, Y and Z are all
read/write and indeed C# code has no boggle doing just that.
Vector3.GetType().IsValueType is true; I guess relying on IsValueType isn't

As far as I understand the Vector3 type: it is a struct with public fields,
are these subject to these quirks too? One wouldn't expect structs to need
getters and setters that somewhat
