Natvis custom view of pybind C++ objects in Visual Studio debugger

[flexorx]

There's a highly useful feature in Visual Studio (not Code) debugger, called Natvis custom view:
https://learn.microsoft.com/en-us/visualstudio/debugger/create-custom-views-of-native-objects?view=vs-2022
One can find STL Natvis XML files in this location:
C:\Program Files\Microsoft Visual Studio\2022\Preview\Common7\Packages\Debugger\Visualizers
Theoretically, it should look something like that:

<?xml version="1.0" encoding="utf-8"?>
<AutoVisualizer xmlns="http://schemas.microsoft.com/vstudio/debugger/natvis/2010">
    <Type Name="pybind11::list">
        <DisplayString>{{ size = {size()} }}</DisplayString>
        <Expand>
            <Size>size()</Size>
            <ArrayItems>
                <Direction>Forward</Direction>
                <Rank>1</Rank>
                <ValuePointer>begin()</ValuePointer>
            </ArrayItems>
        </Expand>
    </Type>
</AutoVisualizer>

Though it looks like Natvis doesn't support function calls, and so one needs to go deeper into PyObjects structure.
Has anyone tried to implement such support?
