In the context of shared libraries, with gcc

is used to make myfunc be called upon loading of the shared library (you
can tell I know what I am talking about here) via some field in the ELF
headers, apparently. Is there any way to get our trusty d compilers to
do the equivalent?

Sure, Ellery, we have this awesome feature called module constructors.
Check em out.

Ehh, I would be using this to initialize druntime...

You could just define _init, couldn't you?

Yes, but there is only one _init, while the above can be used with
multiple functions and thus wouldn't inadvertently cause important code
to not run. If I don't have to, I'd rather not.

Wait, why are you initializing druntime?

Because druntime isn't set up to do it yet for c main calling d shared
lib. You'd think it would need the same sort of functionality when it
does implement it, though.

I don't know if it's automatically linked but here you go:
