Here's my blog announcement about this:
https://dpldocs.info/this-week-in-d/Blog.Posted_2024_09_30.html#import-expressions-do-not-always-need--j

Note that it is different than `-J.`. Upstream -J. loads the 
import("file") from the *build* directory, OpenD import("file"), 
without requiring a cmd line switch, builds from the *source* 
directory.

As a library author and distributor, I find this behavior a lot 
more useful - compiled-in files are extensions of the source 
code, so it makes sense to put them with the source code. And 
when you use multiple libraries, they probably don't want to 
overwrite and override each other, so encapsulating it to the lib 
is sure to work better.

Of course, the same rules work for your own application code too, 
you can import stuff from your source in your modules too, it all 
just works out of the box. And then you can assign it to 
immutable byte arrays or strings (if you use `auto` it is a 
string for historical reasons - remember opend aims to be more 
stable than upstream as well, unless there's a compelling benefit 
to justify the change - but if you specify `immutable(ubyte)[]`, 
it just works, no cast necessary. I think this is also true 
upstream nowadays.)

I've been pretty happy with it.

Yes, exactly. I've been writing D for about 19 years now, there's 
some things I just got used to so I have my blind spots, but 
there's also things that I still think ought to just work. OpenD 
is getting closer and closer to plugging these holes though.

As you can see from the commits, most of these aren't terribly 
complicated to implement.

(some things that are more complicated to implement is like 
`if(auto x; tryGetFoo(x))`, we're still working on that, 
hopefully some day. but in the mean time when pain hits, we're 
open to fixing it)
