Well, -betterC existed even then, but it was *completely* 
useless. It didn't become useful until 2016 or 2017.

But around that same time, going minimal runtime got even easier, 
so I never really got on the betterC train anyway. On my tetris 
webassembly thing last month, I went with a minimal druntime 
http://dpldocs.info/this-week-in-d/Blog.Posted_2020_08_10.html#druntime

And it has some class support too in not a lot of code: 
https://github.com/adamdruppe/webassembly/blob/master/arsd-webassembly/object.d

(and if you aren't doing classes and built-in arrays, you can cut 
a bunch of that out too).

Yes, indeed.

betterC is nice that it gives a library community a shared target 
to rally around, but for your own custom application it is 
probably better to do your own thing (though betterC might work 
for you too, worth considering at least).
