If I made a D library, how easy would it be to use it in other 
languages (C, C++, Go, and Rust)?

D interfaces directly with C, so no problem there.

As far as C++ it should work just as well, there are only a very 
few quirks with that.

Anything that can interface to C can interface just as easily to 
D.

Approximately equally challenging as C++.
You basically depend on `extern(C)`. In D you may gain one substantial
advantage, in that you might create a system to automatically wrap the
D-facing API in `extern(C)` export shims.
So perhaps you can automate a lot of `extern(C)` boilerplate...

You automate pretty much all of it:

As others have mentioned, D can interface with C. D can also interface 
with C++ and with Objective-C. It depends on which language you want to 
interface with, you mentioned C++.
