Trying out C# Caller Attributes

CallerAttributes.cs

public static class CallerAttributeExtensions
{
	public static void WriteCallerAttributeValuesToConsole<T>( this T? obj, 
		[CallerMemberName] string? member = null, 
		[CallerFilePath] string? filePath = null,
		[CallerLineNumber] int lineNum = 0,
		[CallerArgumentExpression("obj")] string? expr = null )
	{
		Console.Out.WriteLine( $"{member} {filePath} {lineNum} {expr}" );
	}
}
