Yes it does?

Indeed, only one or the other. We should really fix this somehow 
though, because opApply sucks with all of D’s different function 
attributes.

I guess because the function calls an un-marked delegate? I’m not 
even sure how I’m able to call it in `@safe` code though, and yet 
it supposedly uses the GC just for iteration? And heaven forbid C 
code tries to call it, since it’s `extern(C)` but supposedly 
throws…
