What's a di file? (sorry google didn't help with that)
It's been my understanding that it's always been illegal to
provide a definition for a function that was declared
previously unless it was declared in a .di file, in which case,
you're not really both declaring and defining it, but the .d
file is used when the module is compiled, and the .di file is
used by other modules which use that module, so the declaration
and definition are not seen by the same run of the compiler.
