Ah okay, you're using a `void()` signature for all wrappers. If 
you don't want to bother with a proper signature (possibly 
derivable from `n`), you need to avoid compiling modules using 
the properly typed declaration and the wrapper module(s) *to a 
single object file*, to prevent LDC from detecting the signature 
mismatch. So if you have one or more wrapper modules containing 
nothing but these mixins, compiling those separately to their own 
object file/static lib should work.
