However, it's still more verbose. My goal was to emulate
almost exactly
what C++ was doing by using a template so you could just write
"fold!('+', args)"
I'm probably missing something, but `fold!"+"(args)` isn't more
verbose than `fold!('+', args)`.
I mean what goes on inside fold. If you look at the C++ example
it's very concise and IMO beautiful:
<typename ...Args> auto f(Args ...args) { return (0 + ... +
args); }
So I wanted a solution that was about the same in terms of
brevity. My first attempt was:
enum fold(string op, Args...) = mixin("Args[0] " ~ op ~ "
fold!(op, Args[1..$])";
But of course this doesn't work.
