It'd cause a linker error though, right? This isn't really much 
different than any other mismatched header - and since we have 
dmd -H, it seems manageable.

I'll write a blog about this when I have time though. Been 
swamped with work lately but I do think there's some cases we 
have to be careful of but it should be doable.
