Hi Alexander,

My answer is quite short, but I discovered a major flaw with the approach 
you propose, and it renders most of it unimplementable. Please see below:

No can do. Virtual functions cannot be templates!

This rules out automatic type conversions. It would have to rely on 
something else to provide it.

Best regards,
