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

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.
