ReplyWhat are some use cases where struct opCall would be useful?
As far as I know, this capability is unique to D. Do any other languages support this?

When the struct is intended to be a function object. I.e., a type that abstracts a function. > As far as I know, this capability is unique to D. Do any other languages support this? C++. Not that that's a good example of what a language should do. :-D T -- What did the epileptic have for lunch? Seizure salad. | |||

Glue code, someone was fairly good about trying to hide all implementation details, contrary to popular belief, syntax sugar has syntactic meaning. 95% of the base cases of the fundamental syntax are "scary hidden control flow" escape hatches. In the most exterme cases you can nest structs with opDispatch, opCall is fairly mild mannered bit of meta programming hacking. | |||

I've used it my Lua wrapper to give it a slightly more natural interface when calling Lua functions from D: https://github.com/BradleyChatha/lumars/blob/master/source/lumars/function_.d#L138 | |||
