Details

I have a C# class library which I use in Python. I have a Point class (a code snippet):

public Point(double x, double y)
{
	this.x = x;
	this.y = y;
}

public override string ToString()
{
	return $"Point({x}, {y})";
}

This is more a question than a feature request.

When parsing JSON files, I need to sanitize the field names so field with spaces becomes field_with_spaces.
I want to preserve the original name as well, metadata about the column if you like :)

There is a metadata field on StructField, but it is internal.
Why is this internal, is it possible or desirable to expose it?

I just noticed this while testing the other PR:

most tests have a clickable got-to-source link, but some don't.

I can't see any difference between the ones that do, and the ones that don't.
