This whole topic is a bit of a thorny one in that D's design is
trying to
avoid some of the problems that allowing const T& to take
rvalues in C++
causes, but it makes a situation like what you're trying to do
annoying to
handle. And auto ref doesn't really fix it (even though that's

Oh, and a related question: what is the best way to pass in an
associative array like CustomStruct[string]? I can't say I'm too
clear on how AA's are managed/implemented. Do they have value
semantics or reference semantics? What about lists?
TL;DR: what should I use if I need C++'s const& for a param?
Long version: I have a big struct provided by a library and I'm
trying to pass instances of it to a function that will never need
to modify the passed in value. Naturally I want to pass it
efficiently, without incurring a copy. I kno
