Indeed, that is an oversight on my part. However, that's just a 
typo I happened to include in my last attempt. I use foo() and 
others, and .def exporting them etc. Tried various things based 
on the examples I linked.

Well, as I'm new to D this isn't something I have insight into. 
However, this being and advertised feature of the language, I'm 
surprised to see that you dismiss it so casually. Also, for my 
project, I mostly need interop with C libraries and D would only 
serve as a glue, so I don't really need several features like GC 
etc. `betterC`, at least what I thought it was supposed to be, 
seemed to be a good fit for what I need.

Perhaps, but this doesn't help me much.
