Looking for feedback on Nim for Beginners #27 Object Variants

[kobi]

Yes, for example json module is built like that. when you want a sequence of 
objects, but don't want the complicated inheritance part. I care less about the 
speed, things are already quite fast, and more about the use cases it enables. 
the style of programming, and ease of modifying and changing things along the 
way (maintainability and complexity). imo, these should be the perspective or 
talking points.
