Not quite the same as this is a fold over a TypeTuple/AliasSeq.
You could of course do:
only(args).fold!"a + b"()

That is not what "fold expressions" mean. Fold

Ok. That's what I missed.
If you look at the C++ example it's
very concise and IMO beautiful:
auto f(Args ...args) { return (0 + ... + args); }
But the shown `fold` implements the functionality of that C++ language

Luckily that hardly matters, you just need to define one generic

If you mean runtime interpolation, that means one has to bundle
the interpreter with the executable, and sacrifice alot of code
speed. I recall that there
