@suetanvil how in the world is this C++ ? can you teach me abou the $ and $$ thing? 
$ is considered a valid ‘word’ character by C and C++ these days, so $$ is just a function. $ is a variadic function template that constructs a list.
I plan to put this on Github in a couple of weeks; ping me if you’re still interested.
@suetanvil im very interested!
@suetanvil Clever and hilarious, thank you 😀
If anyone is still interested in this, I've published a writeup on my blog at
