So, what you're saying is that DMD doesn't have its own linker? 
That never occurred to me.

On the other hand, if D uses a linker previously built for other 
compilers (C or C++, I assume) I'm surprised that this 
already-existing linker doesn't have such an error message.

On the other-other hand, if linkers are used for building both 
executables and libraries, it does make sense in a way. I mean, 
otherwise the linker developer would have to allow for a command 
line switch telling the linker the specific output of the build: 
library, or executable.

But this now sounds like a discussion for another venue. Not sure 
which, so instead, I'm going to write up a little note to post on 
my monitor bezel, something like:

Does your code have a main() function?

I guess that will have to do. Thanks for the discussion, guys. 
It's been fun.
