I was curious how C++17's std::variant compared to the options
we have in D, like Algebraic and SumType, so I did a simple
comparison of the generated assembly for each of them. You can
read about it at the link below. And as you can probably guess
from the title, D comes out ahead, in the end.

This is my first attempt at sharing something like this, so any
comment or feedback is very much appreciated!
getting typeinfo in D leads to a double indirection. Making a
tagged union is clearly a better alternative and the results of
SumType vs Algebraic are not a surprise. I pointed this to the
main maintainer of D-YAML a while back but at this time there was
more serious bottlenecks. If you read this "El Pinguino"...
