Considering D is billed as a multiparadigm language, I'd be 
surprised to hear that the intended usecase does not include 
"functions with more than two parameters". This comment seems 
quite far from practiced reality. In any case, passing a struct 
is a horrible solution, because, again, there is no way for 
structs to even enforce that *all* fields were set, let alone 
some subset, short of spamming Nullable.
