Are these resolved at compile time (before the executable is 
installed on the computer) or are they resolved at runtime?

I guess there might be instances where you might want to consider 
to change the entire data layout to fit the hardware, but then 
you to some extent outside of what most D programmers would be 
willing to do.

The goal is to make it look like a regular C++ library, no extra 
syntax.

Just write the whole runtime in Objective-C++. Why would it be 
ugly?
