Why is std.variant bad?

[monkyyy via Digitalmars-d-learn]

This was before my time. I was under the impression that it was 
somehow class and oo related badness when people talked about 
using TypeInfo; but when I my own experiments say that typeinfo 
is just another tool

I see 3k lines of code compared to my 50; Im going to say its but 
the postmorden seems wrong.
